When I started the process of critiquing the Lancet paper I thought I was going to strip it down to its component parts. However, I have come to realise this would take far too long. Even longer than it has already taken – which is probably too long.
A truly detailed critique would mean that virtually word every would need to be deconstructed, expanded and explained. Instead, I am going to try and condense the key points, without getting dragged down into too many statistical rabbit holes.
I suppose that, in part, the difficulty in deconstruction represents a key defence of the paper. It has been so cleverly written, so well-guarded on all sides by impenetrable jargon, that it can take pages to explain just one word they have used. No journalist stood a chance; they just repeated the press release virtually word for word. As did everyone else. Ending up with something like:
Statins are even more effective, with fewer adverse effects than even we thought, say Oxford based researchers in the Lancet. (Beep) message ends.
Of course, the paper itself wasn’t written in quite such a jaunty manner. Here is one turgid passage from the paper itself:
‘Biases can also be introduced by making non-randomised comparisons between rates of events across different trials, not only because the outcome definitions might differ but also because the types of patients studied and the duration of follow-up might differ. Such between-trial comparisons might be seriously misleading, which is the reason why meta-analysis of randomised trials involves statistical methods based on the within-trial differences in a particular outcome.
As a consequence, health outcomes do not need to have been obtained in the same way in the different randomised trials contributing to a meta-analysis for comparisons of the rates between the randomly allocated groups within each separate trial to provide unbiased assessments of any real effects of the treatment.’
If you did manage to get to the end of that, what do you think it meant? And why did they write it? What are they saying here?
In truth, there is only one word in that passage that you need to take note of, for it carries the weight of all else on its shoulders. It is the word ‘might’, which I put in bold. They used this word because they didn’t want to address the fact that the rate of adverse effects seen in different statin trials differed so wildly. From 3.2%% to 94.4% for the statin. And from 2.7% to 80.4% for the placebo.
Figures that call into serious doubt, the validity of the entire data set. Which should lead to questions such as: Why is the measurement of adverse effects in clinical trials such a sprawling mess, when it is so critically important?
Researcher one: ‘I measured Mount Everest as being eight thousand metres high.’
Researcher two: ‘Funny that, I measured it at two hundred and forty thousand metres.’
Researcher one: ‘Measuring things can be tricky. We’ll just include both figures in our report.’
At best, each trial was recording adverse effects in such a different way, the data itself becomes almost completely meaningless. At worst, there was data manipulation going on to ensure that adverse effect rates stayed exactly the same for the statin and the placebo. No matter what the absolute rate. Which brings up the possibility of data fraud. And no-one wants to open that can of worms.
Still, the authors of the paper faced a tricky problem. How do you get around the fact that the ‘between trial’ rates of adverse effect varied thirty-fold for both statin and placebo arms. Particularly when placebos are supposed to be inert ‘sugar’ pills. And therefore identical? [More on that myth at some other time].
The answer was to decree this was completely irrelevant, and the huge variations not only could, but should be completely ignored. Which left them in the far more comfortable situation whereby they only had to explain or compare the rates of adverse effects within each trial.
Their comfort, in large part, came from the fact they already knew the rates for placebo and statins would be virtually the same within each trial. How so? Because they had previously responded to an open letter in the BMJ discussing this very same issue in 2014. Text written by me.1
Yes, they dismissed this massive data anomaly in 2014, and dismissed it again in 2026. Might is the word they used for this task. Sitting within the sentence ‘between-trial comparisons might be seriously misleading.’
A lot of things might be misleading, but a lot of things also might not be. However, it is not really a scientific word, is it? In this passage it represents an evidence free opinion. You would think ignoring something as important as this would need to be supported by some facts, a bit of research, a touch of evidence even? Not so. The word might will do quite nicely, thank you.
And, whilst the passage surrounding that word may sound scientific, if you take a little time to think about it, it crumbles into gibberish …dressed up to sound like science. Just look at the first sentence, and read it slowly?
‘Biases can also be introduced by making non-randomised comparisons between rates of events across different trials.’
What, exactly, is a non-randomised comparison in this case? How can you possibly randomise data that has already been collected? Especially if those data have been obtained from double blind placebo controlled randomised clinical trials in the first place. We need to randomise already randomised data? Any thoughts on how that could be done? What would it even look like if we did so?
To further sustain their analysis, they brushed aside any trial that they didn’t like the look of e.g. METEOR or IDEAL. They decreed only trials with one thousand participants, or more, were worthy of consideration. METEOR the trial where 80.4% had adverse effects on placebo – had a mere 984. Dismiss!
Removing the METEOR study was not an act of randomisation. It is what we humans call cherry picking the data to suit our argument. They got rid of IDEAL because it looked at two different statins. Not statin vs. placebo. Dismiss!
Then, in a stunning contradiction, the CTT Oxford found themselves content to carry out a ‘meta-analysis’ ‘of all these wildly different trials. And this caused them no problem at all. A meta-analysis, is, by definition, a case of bringing together various clinical trials of interest in an area and aggregating the data.
There will always be differences between trials. Different ages of participants, different underlying medical conditions, different end points etc. However, if you state that you are unable to do ‘between trial’ analysis, because the trials are too different, you cannot then go on to do a meta-analysis. Yet, they did.
Anyway, here we are… I looked at passages like the one above, and all sorts of flashing red lights went off. Most people, I suppose, just blipped over it. ‘Oh, long words, statistics…. Forget it, move on.’ Most people in truth, will never read the paper … ever. Most doctors will not read it either. A few. A very, very, few may read the introduction and conclusions – and that’s about it.
Scientific papers in medical journals are not designed to be read nowadays; they are designed to intimidate. Dense medical jargon, unknown acronyms, all written in the dullest possible passive voice. Then, sprinkle in a few statistical tests no-one has heard of, and your castle of intimidation is complete. Defences bristling.
In this case. ‘Oh yes, we used a false discovery rate analysis…’ They used a what? I had never heard of it, and it took me a week to find someone who had. I looked it up on Google, but it still made very little sense, at first.
My current broad-brush interpretation is that the false discovery rate is a way of immunising against uncommon serious adverse events. These can turn up in early-stage exploratory studies, with small numbers of participants. Say for example, you do a Phase One study on fifty people, and two cases of liver damage turn up.
Four per cent possibility of liver damage …OMG! That could end your drug. But of course, it could just be chance. Every week someone wins the lottery, at ten million to one. Thus, in order to prevent a chance finding from killing your drug stone dead, you set a false discovery rate (FDR). Obviously, you need to keep a sharp eye on the liver issue. It might not have been chance.
However, FDR it is not an appropriate test for randomised confirmatory studies with thousands involved i.e. the exact same studies they chose for their meta-analysis. Here, you are supposed to have removed chance, as far as possible, by looking at thousands of participants over several years of study. It is, kind of, the whole point of such studies. Remove chance, disprove the null hypothesis. Sell your drug, make billions.
Yet, despite this, they set an FDR of 5% to analyse studies long since completed. The 5% rate means that you expect that one in twenty of the identified safety signals are expected to be false positives i.e. chance findings.
Which safety signals could be missed, or ignored, by doing this? How about rhabdomyolysis … severe muscle breakdown carrying with it a mortality rate of around 25%. It is a known adverse effect of all statins, though rare(ish).
Let me take you back in time to one of the most recently launched statins – cerivastatin. What, you mean you’ve never heard of it? It was the most potent statin ever made. Here is a paper from 1998. ‘Clinical efficacy and safety of cerivastatin: summary of pivotal Phase IIb/III studies.’ 2
‘…cerivastatin is an effective, well-tolerated, and safe treatment for the reduction of LDL cholesterol and other atherogenic lipids in primary hypercholesterolemia.’
‘There was no significant difference between the incidence of adverse effects with cerivastatin and comparator statins.’
Now let me take you forward a mere three years to 2001. ‘Withdrawal of cerivastatin from the world market.’
‘Cerivastatin was recently withdrawn from the market because of 52 deaths attributed to drug-related rhabdomyolysis that lead to kidney failure.’ 3
Do you think CTT Oxford included data from the ‘double blind’ cerivastatin trial? The one where it was found to be safe and effective? How would the FDR analysis have done on that one? Who knows, because obviously the CTT Oxford ignored this ‘safe and effective’ drug, and the RCT that launched it.
Let me summarise the wonder drug cerivastatin for you. Statin found to be safe and effective in clinical trial, stop. No more adverse effects than any other statin in double blind placebo controlled clinical trial, stop. Found to kill people shortly after launch. Stop.
Do you think serious adverse effects can be missed in clinical trials? You may want to look up Vioxx on Google. Actually, the serious adverse effects were not missed in this case, they were deliberately hidden. Costly little oversight.
Initial Litigation Settlement ($4.85bn): In 2007, Merck paid $4.85 billion to settle roughly 26,000 lawsuits from individuals alleging injury, a move that followed several high-profile jury trials.
Securities Class Action ($830m): In 2016, Merck agreed to pay $830 million to settle a lawsuit with investors who bought securities between 1999 and 2004, claiming the company misrepresented Vioxx’s safety
Anyway, missing safety signals happens all the time. The first time anyone noticed that statins increased the risk of diabetes – by a large amount – was with the JUPITER study on rosuvastatin. Which was one of the later studies, on one of the very last statins to launch. But all statins have this effect. So, how come no-one noticed it before? Your guess is as good as mine. FDR anyone?
Of course, in what I consider to be a perfect irony, the greatly increased risk of rhabdomyolysis with cerivastatin was only picked up by observational post-marketing safety studies. The type of study that might be biased. The type of study that the CTT decreed to be worthless and can therefore be ignored.
Perhaps the CTT Oxford should demand that cerivastatin is brought back onto the market? After all, it was found to be perfectly safe in the randomised controlled double-blind study. The only studies we can rely on to provide objective data. Ho, ho.
Perhaps you can see my problem here. I read a paper, and see flashing red lights all over the place, but trying to explain why they are flashing … even a single word like ‘might’ can take pages to untangle. Why did they use it, what is the context, the background, the rationale … as for FDR …
For most people a clinical paper is an arcane and impenetrable document – virtually unreadable. However, I do know this world … all too damned well. I may not follow all the highly complex statistical methodology used, but I know enough – at least to ask the right questions. Most people are effectively frightened off.
‘FDR, what’s that, I don’t understand it. I may sound stupid if I ask questions. I shall keep quiet.’ Time, I think for one of my favourite quotes from Michel de Montaigne.
‘Difficulty is a coin which the learned conjure with so as not to reveal the vanity of their studies.’
I certainly do not read medical research papers the same way others may do. I start from a different place. Which is that I do not believe a single damned word they are saying, then work backwards towards the truth – if I can find it. It is not a world I particularly want to inhabit, but here I am. I like to think of my approach as constructive criticism. But then, I also like to think of myself as handsome and witty.
Am I alone in having such a cynical view? Am I a mad conspiracy theory nutter, railing against the deep state? I don’t think so. I am certainly not alone. Here is what Marcia Angell has to say about medical research. She edited the New England Journal of Medicine for many years. It was, and remains, the number one medical journal in the world. I imagine she could be considered a reliable witness by the mainstream.
‘It is simply no longer possible to believe much of the clinical research that is published, or to rely on the judgement of trusted physicians or authoritative medical guidelines.
How about Richard Horton, long term editor of the Lancet, the number two medical journal in the world.
‘The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue. Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness’.
You think peer review would pick up egregious errors and data manipulation? Here is what Horton has to say on that issue
‘Editors and scientists alike portrayed peer review as a “quasi-sacred process that helps to make science our most objective truth teller. But we know that the system of peer review is biased, unjust, unaccountable, incomplete, easily fixed, often insulting, usually ignorant, occasionally foolish, and frequently wrong.’
Another of my favourite quotes comes from Drummond Rennie.
The Trouble with Medical Journals carries on the insightful, acerbic criticism of biomedical publication started by Drummond Rennie1 (the founding father of peer review research and JAMA Deputy Editor) who wrote more than 20 years ago:
“There seems to be no study too fragmented, no hypothesis too trivial, no literature citation too biased or egotistical, no design too warped, no methodology too bungled, no presentation of results too inaccurate, too obscure, and too contradictory, no analysis too self-serving, no argument too circular, no conclusions too trifling or too unjustified, and no grammar and syntax too offensive for a paper to end up in print.’
Print that out, and stick it on your wall. I have, because it is my starting point when I read a clinical paper in a medical journal.
I knew straight off, from reading the title of the paper, that we had nonsense on our hands. The paper was called. ‘Assessment of adverse effects attributed to statin therapy in product labels: a meta-analysis of double-blind randomised controlled trials.’
Utterly misleading, right from the very start.
That title leads to the first obvious question. Or at least it should. Did they bother to find out how many people read product labels? [The product information leaflets found inside boxes of prescribed medications]. More specifically did they try to find out how many people read statin product information leaflets?
The answer to both questions is a resounding no. They did not. Nor do they mention any other research they could use to support their central argument? Not a single scrap.
Next question. Did they carry out any original research to find out the effect, or otherwise, or reading a product label on reported adverse effects. No, they did not. There was nothing done in this area, at all.
Given this, how could they possibly make a connection between adverse effects reported in observational studies, to the information found on product leaflets. Again, the answer is that they could not …. they didn’t even bother. They simply assumed it ‘might’ happen. Yup, bang on proper research. Assumption laid upon assumption.
The correct title for this paper should have been. ‘A meta-analysis of adverse effects of statins found in selected trials.’ Because that is what took place. They then tacked on an assumption, based on nothing, that the information on product labels leads to massive over-reporting of adverse effects in all observational studies. Which can therefore be ignored. Utter and complete rubbish.
As for myself. I assume that the reporting of adverse effects is based on the phases of the moon in the constellation of Sagittarius, and I have done just as much original research to support this hypothesis as they did i.e. none.
Despite this, they ended up making the following, potentially dangerous, recommendation
‘…there is a pressing need for regulatory authorities to require revision of statin labels and for other official sources of health information to be updated, so that clinicians, patients, and the public can make informed decisions regarding the balance of the benefits and risks of statin therapy.’
I say dangerous because muscle pain, for example, may herald severe muscle damage that can – in some cases – end up being fatal (see under cerivastatin). And if you don’t know statins can damage muscles, because all information on this has been removed, you may not take any action on symptoms until it is too late. ‘Lawyers, please start your engines.’
As for the ‘meta-analysis of double-blind controlled trails’ part of the title. That refers to research on adverse effects found in randomised controlled trials. Which was only tangentially connected to product labels. If at all.
In short, there was only one piece of new research done – the meta-analysis of adverse effects inf RCTs. Which was hardly new. Yet they claimed to have carried out an ‘Assessment of adverse effects attributed to statin therapy in product labels.’ Well, they made no such assessment, so no such claim could possibly be made.
A title as misleading as this, heralds what is to come. Several pages of quasi-scientific nonsense. Yet, the world lapped it up.
But what of the adverse effects?
I may look at them next. Or I may have run out of energy.

Dr. Malcolm Kendrick 
I despair of “modern science”, I really do.
Science is fine. It’s one of our greatest assets as a species.
It’s the cheats and parasites who gather around it that are the problem. Like vultures at a carcass.
The root problem is that our society somehow encourages such parasites. We see them in business and politics too.
“Science is fine.”
No; some of the sciences may be reasonably healthy but the Church of Science is in ruins.
Maybe the ruin was caused by the huge expansion of the numbers of scientists after WWII or by the concomitant flows of government subsidy. Or maybe it’s just another example of a human activity becoming a business and then degenerating into a racket. Such degeneration in a bureaucracy typically takes two or three generations – which is about as far as we are from 1945.
Science is, of course, fine. It is humans who distort and damage it. As per usual.
“our society somehow encourages such parasites.”
A huge “somehow” is money. Government grants + Big Pharma bucks = Toxic corruption.
On one hand you can take drugs and take your chances and on the other hand you take no drugs and take your chances. There is no proof that taking drugs leads to a longer, healthier life. I choose option number two as I prefer not to be poisoned by toxic drugs. Actually my brain tells me this speaking to my heart and soul.
The trouble is, some drugs are essential and life would be intolerable without them. Many people don’t have the luxury to adopt the ‘my body is a temple’ approach to drugs.
Since offering my comment on your previous essay I have further reviewed the issues involved and concluded:
1 – yes, Kaiser Permanente does have the data you need to settle this;
2 – No, I do not think the lancet authors are duplicitous lying SOBs, I think they’re caught between rocks and hard places and trying desperately to wiggle their way out by ultimately saying nothing they could be hung on by either side; and,
3 – the underlying problem is that the “gold standard” methodologies, whether at the experimental or analytic stages, simply do not work for long term drugs like statins.
So – if you want to determine whether, or to what extent, statins work what you need to do is see whether people who were correctly (i.e. in response to a correct diagnosis) prescribed statins and took them over a long period of time lived longer, and/or better, than those who (correctly) got the same prescriptions but choose not take them for the long term.
This approach eliminates three of the major factors limiting the accuracy and value of long term clinical trials: no placebo effect; diagnosis confirmed by autopsy; and, no sorting (data contamination) effects arising from interactions between testers and testees.
So, bottom line, if some large number (like 931,822) people for whom we have subsequent autopsy or morbidity conference data were prescribed statins in some year like 2000 and many (e.g. 241,455) of them did not renew their prescriptions, then simply looking at the number and scope of subsequent medical interventions in the lives of the members of both groups can tell you definitively whether, or to what extent, statins work – and you can then further refine that by considering available data on the factors differentiating those who continued to take the medication from those who did not: things like weight, activity, job stress, or addiction (food, medical attention, alcohol, …)
Brilliant Dr Kendrick but ever so depressing. The entire edifice of modern medicine [sic] is based on a mountain of lies, so what to make of the treatment we get when (if we’re lucky, or perhaps not) we get to actually see and talk to a doctor, a rare event these days? I raised the issue of the information leaflet once and was told that, ‘Oh they have to say that for legal reasons, just ignore it’.
BTW, I found out about FDRs within 30 seconds of reading about them in your essay:
“The false discovery rate (FDR) is the expected proportion of type I errors. A type I error is where you incorrectly reject the null hypothesis; In other words, you get a false positive.
This is the condensed version. What is so infuriating about this, is using language as a weapon to hide the truth but wait, doesn’t the mainstream media do this as a matter of course but without all the confusing words?
A good meta-analysis of the meta-analysis. It is not worth tormenting yourself more. Vioxx has been one of my favourite they-knew-but-hid drugs for many years. I read Marcia Angell’s book “The truth about the drug companies” 20 years ago and maybe that is where I picked up the Vioxx case. I have never been in a position where something I worked on could cause death but wonder how it feels when stuck with that problem. This would be a good research project though maybe impossible to get honest answers.
I stopped taking statins years ago after reading your original ‘blog’. Now nearly 80 I would like to thank you for my health and for saving the NHS some money. Unfortunately, I cannot say the same for the nurse who conducts my annual review – frustration and ‘well it’s up to you’. Today, you are not allowed to show independence. My online medical record shows repeated ‘refused COVID vaccination’ ‘refused statins’. When I show this to friends they warn me I may get struck off. How close is that?
Isn’t the (completely justified) criticism of scientific writing the same as that of general academic publications – meaning that “publish or die” holds sway ? If you don’t keep churning ’em out you’re dead meat and you won’t get that next grant ?
Btw, ‘turgid’ is my new favourite word. [grin]

Excellent as usual!.
Were the placebos used in different trials ALL true placebos, ie, insert saline etc?
I certainly hope you have the energy to continue Dr Kendrick. I hope you gain a measure of strength from your supporters who profoundly value your work.
Thank you
Thankyou so much for your comments on this article. I have tried to read the article and very quicky found that I could not understand much of it due to the arcane style of writing. This makes one quickly feel too stupid or uneducated to understand it. I could say the same for many medical articles, and I am a GP with 45 years of medical practice under my belt. So it is all too easy to ‘trust the experts’ (they are professors from Oxford after all, and get published in the Lancet) and take the conclusions at face value. As you point out this is by design and the intended outcome.
There are associated problems here. First, this weird and excruciatingly boring way of writing has become the accepted form. This experiment was carried out, these data suggest, a heuristic analysis of the data… If you try to write in an interesting way, it will be rejected as not ‘science.’ Which is, of course, utter nonsense. This means that articles simply are not read. You can include the most egregious rubbish, confident that it will never be seen.
So, we are all left with the press releases, or some superficial media article. Two minutes on the BBC news at ten. Everyone assuming that ‘someone else’ must have put in the time and effort to ensure the science is sound, the conclusions valid etc. Bad news, there is no ‘someone else.’ Peer review…. don’t make me laugh.
The review in people’s minds is, pretty much as you describe. This has come from Oxford University, written by a bunch of eminent professors, and published in the Lancet. Who am I to question the mighty ones?
I would be happy if the fact that articles came from Oxford and ended up in the Lancet meant we could fully trust the contents, and conclusions. However, we have long since moved far, far, away that that position.
Evidence based medicine has been replaced by eminence based medicine. [Not my joke, but a good one nonetheless].
This was another interesting expose. I find myself drawn in because the material is well researched and the ‘conversational’ tone running through it. Prompts more response/ reaction than many a dullard preaching from notes, meaning one finds oneself thinking rather switching off.
EBM requires numbers–and numbers requires funding. Who has funds for EBM except those who can profit by it?
It seems that any real, alternative science will be messy, low in numbers, controversial, and unable to adhere to the EBM philosophy. Hence, a great deal of caution will have to be exercised when reading any alternative science. Still, better to spend time filtering out noise to find than to spend time where no signal is likely to be found.
Oh I do love you Malcolm …..as a 51 yr retired RN I’ve seen so many red flags for many years & I thank you for your information and, not least, your humour.
We need a bit more of the latter these days I feel.
And I just love Drummond Rennies quote ever since I’ve read it in Doctoring Data.
I’m going to do exactly what you’ve done….and I may even do a letter box drop with it when we have the next plandemic.
“I suppose that, in part, the difficulty in deconstruction represents a key defence of the paper. It has been so cleverly written, so well-guarded on all sides by impenetrable jargon, that it can take pages to explain just one word they have used. No journalist stood a chance; they just repeated the press release virtually word for word”.
Of course, if we had a free, honest media, it wouldn’t be just one journalist; there would be literally scores or hundreds of them working away at the task like ants.
My inclination when faced with such a challenge would be to meet it head on: use as many pages as possible to explain every single bit of deception in the paper.
Of course I do not mean that Dr Kendrick should try to do that single-handed, although he has done an admirable job – as good as any individual could do.
“But then, I also like to think of myself as handsome and witty”.
Most of us would certainly agree with that! Moreover, I personally adore anyone who adores Montaigne. One of whose best ideas was the deliberate suspension of judgment when sufficient evidence is lacking.
Don’t despair, Malcolm. Your views are gaining ground. My GP bless him hasn’t pushed statins at me even though my cholesterol levels are (thankfully) a tad high. Okay, a sample of one. But not insignificant.
My OH was on statins for a number of years. After having read Dr MK’s book and, armed with relevant info, he tried to discuss the risks and benefits with his GP only to be met with an incredulous response! Over a number of weeks following, he was contacted by a number of GPs in the Practice in an effort to persuade him to take ‘the newest one’ (better than the previous one. No mention of the patent having run out for the previous one!!). OH ‘won’ and tho’ the subject is mentioned on his annual reviews it is not pushed when he politely declines.
Dear Dr. Kendrick,
wrt your last sentence:
“I may look at them next. Or I may have run out of energy.”
I suggest to listen to this song by Kris Kristofferson:

Take care and please continue!
J. Harter
Read all your articles with interest . Do you give advice ? Always look forward to your posts and hope this finds you well 🤗
I do so hope you do not run out of energy Dr Kendrick. I am sure your posts are greatly valued by many people like myself who are out to get the truth. I sadly no longer trust ‘the science’ nor the NHS medical system and it is a long hard road trying to take responsibility for one’s own health when there is such rubbish written claiming to be valid research. It is very refreshing to have (your) unbiased views based on facts not fiction and corruption. Long may you continue. I truly value your comments, and your wit, and share your frustrations with ‘the system’. It is difficult not to be cynical. With my sincere thanks, not just for the contents of your articles but also for the time and effort you put into producing them and in your own extensive research in order to do so. Very best wishes.
I do not have a scientific bone in my body, but I love the beauty and clarity of the English language in the hands of a good writer who knows how to use its richness to express his thoughts. I am the kind of pedant who points out the difference between disinterested and uninterested, or between may and might. When I read the sentence which you quote near the top of the article, beginning “As a consequence..” I think several things, some of which I prefer not to commit to print. What is the subject and where is the object? Am I reading a sentence which can be analysed grammatically? When the writer started to write it, did he know what he wanted to say? When he finished it, did he think “Yes, that was well expressed”? Or perhaps, “That will have them properly flummoxed!” I tend towards the latter conclusion.
Thank you for wading through verbal sludge yet again. We are grateful that we don’t have to do it. As for patient leaflets inside little boxes, no doctor has ever prescribed medication and told me to be sure to read them. Not ever.
I completely agree, Heather! Moreover, when people accuse me of pedantry I reflect that writing clearly is an important part of thinking clearly. The two go together. It’s been said that if you can’t teach something, you don’t fully understand it. The same goes for writing.
Good to see you returning to a core subject Malcolm.
Things are changing, not necessarily at a policy level but with individual clinicians.
Here is Perth, I visited my GP recently who proudly showed me a Claude AI tool he have built for looking at major CV studies and calculating ARR/RRR, NNT, etc.
He was most excited at dismantling WOSCOP’s and the like.
And then before we even got to my ailments – mentioned he was currently reading Doctoring Data!
I hope all is well with Family.
Some green shoots of independent thought from doctors… we can but hope. My worry about AI is that it could just end up reinforcing the status quo. In that, the vast majority of information it will source (esp with cholesterol/statins) will be entirely supportive of both the cholesterol hypothesis and the ever increasing use of statins. Can AI actually, yet, think about things from first principles, and… actually think. Although I am not sure if I like the idea that much. Who knows where the thinking may go. To quote someone or other. ‘If an animal could speak, we could not understand it. They would have no conceivable share in our world. Their thoughts would be of things unknowable to us.’
For now, I am relying on my brain.
For matters mostly biological I pose my query to 3, sometimes 4, AI LLM’s. The one that impresses me the most is https://alter.systems The replies can be staggeringly diverse.
AI doesn’t and cannot think. All answers from these tools are based on the LLM’s that have been fed in/used in training the tool. If the input is faulty then so will be the output, GIGO. Medical AI tools ‘can’ be useful if based upon actual/real data, eg. Breast Screening, but as you say if the input data is corrupt/biased then so will be the answers. The human brain is the best tool we have, developed over millions of years. Anyone who thinks AI is the answer clearly hasn’t understood the question !
i have used AI to research MetS and related subjects. I would add that you need to begin with a solid and extensive body of knowledge so that you know how to frame a query effectively. You should also use two or three AI engines. And ask each AI engine how it has balanced the lipid hypothesis Vs inflammatory hypothesis. And ask the same question to each AI engine on different days – you will get different versions of the responses!
And then extend the queries to the causes of inflammation ( is it sugar, seed oils, SIBO …. ) or the mechanism of endothelial damage assuming that the lipid hypothesis is correct.
I have been astounded at the depth of ‘knowledge’ (or should that be ‘facts’). But it seems impossible to get any of the AI engines to express an opinion in support of one view or the other. And querying the probalistic programming in use, this is hardly surprising.
I have to say Dr Kendrick quite encouragingly in recent years any NHS GP I have explained to the reasons why cholesterol does not cause heart disease, saturated fat cannot clog arteries and statins reduce risk by an almost imperceptible amount, all very much along the lines of The Clot Thickens have been open to listening and even curious to find out more. I think theyre just astonished to find out things are not as they assumed. Being given very sound reasons why I shouldnt take statins its always accepted. Thats at the GP level though of course.
Glad to hear it. Perhaps change is coming.
You have that rare and invaluable ability, sadly lacking in the world of ‘science’, to render & communicate complexity into essential simplicity, which is digestible to a non-science based audience. Thank you!
As a former employee of one of the largest pharmaceutical companies on the planet (working as an administrator in an R&D department), I was privvy to many instances of gross and blatant manipulation of clinical trials’ data to achieve the desired outcome in terms of their corporate interests.
Unable to stomach the corruption, I eventually resigned, appalled and incredulous at the lack of integrity and/or a moral compass of so many of my gifted and highly intelligent colleagues.
According to my sister, her daughter resigned several years ago from her editorial job at The Lancet because she felt that politics were displacing science to such a degree that she was no longer happy working there. Fortunately, she found more congenial work fairly quickly
It is a sad situation. Increasingly, organisations change. To become overcome by a different tribe with different, usually financial interests, overwhelming any other concerns. I am unsure how to stem this tide.
The assumption that any prescribed medications even come with an information sheet inside the packaging makes me laugh. They’re non existent and have been for decades in any prescription I’ve ever picked up at my pharmacy in Australia. Perhaps twice, a pharmacist has handed me a print out when I’ve commenced a new drug. That equates to about a 5% incidence.
The subject of AI has been mentioned here, I came across this just now:
https://garymarcus.substack.com/p/have-llms-improved-patient-outcomes
Cardiologist/author Eric Topol tends to be more bullish than I am about AI in medicine, but in his latest post he concludes that at least thus far there is “very little evidence for LLMs benefiting patients or doctors for health outcomes” (aside from helping with administrative work and the like).
As Topol notes, his review was partly inspired by this recent editorial in Nature Medicine, which points in the same direction:
Computers are not flesh and blood so they cannot have an inkling of what they are “talking” about, they are just generating strings of words they do not understand.
Any adult who has spent time helping a child learn to speak know that understanding comes from primarily from the physical interaction of the child with his/her environment and learning the words and stock phrases that such experiences provoke, from engaging with real people in the real world.
Sophisticated machines can handle input data much faster than the human brain, but to call that intelligence let alone consciousness is to change the meaning of these words.
Even the word-correction software used on most modern computers makes ridiculous errors. A recent hospital discharge form listed me as having had 2 previous hysterectomies (sic), when my single womb is still where it used to be (more or less), and the doctor who signed the form simply missed the erroneous vowel presumably inserted by the computer. AI scales that kind of thing up to a monstrous degree and therefore needs to be kept on a tight leash by an alert human boss.
Modern medicine is not science – in fact the polar opposite. In ‘science’ the immediate response to a new theory is to either attempt to replicate the result, or to disprove it. Sometimes the same thing, and an activity that even the proposer will take part in. And even the ‘best’ theories are never settled – one black swan may be the end of the theory, or lead to a fundamental revision.
Rory Collins and his ilk certainly do not fit within the definition of a scientist. Perhaps more akin to leaders of a religious cult, or (with apologies to Monty Python), the Spanish Inquisition.
To some extent this is a problem caused by the ‘silo’ approach to medicine. Issues are either cardiac or endocrine or hepatic. It’s as if you attend medical school for 5 years and learn everything about the fives times table, and your associates are learning all about the eight times table, or three times table. Compare that with an engineer, who needs to understand concrete strength, ground conditions, cable stresses, shear point of bolts etc or his bridge will collapse.
I have been researching my own health over the last 12 months, and feel tremendously let down. 30 years ago I was diagnosed with Non Alcoholic Fatty Liver Disease, and was told that as I was ‘asymptomatic’, I shouldn’t worry about it. (To add insult to injury, I have recently discovered that when GP records were digitised some years ago, this diagnosis wasn’t carried forward – so my current GP was unaware.) 6 years ago I had a heart attack, and was prescribed the standard package of drugs. I quickly discovered that one of those drugs was designed to slow my pulse, even though my resting heart rate was 45bpm – it took a visit to A&E to take that off my prescription. 18 months ago I was told – at my annual heart review – that I was officially pre-diabetic. When l looked back at my HbA1c, it had jumped from 35 to 39 on starting statins, and then took 5 years to reach 42. I stopped statins, and went in a keto diet. My HbA1c is now 33, my fatty liver has gone, my HDL has shot up, and my triglycerides have shot down. Metabolically I am now as healthy as in my 20s.
i now believe that I have / had one problem – insulin resistance (or hyperinsulinemia, whichever came first). But I have been treated as if I had a five times table problem, a three times table problem, and a seven times table problem. If I was a bridge, I would have collapsed! Even worse, the statin and beta blockers caused harm. But because I was being treated by silo I now have 30:years of metabolic damage, at least in form of calcified atherosclerosis (and two stents).
If the dots had been joined up, I could have started putting things right 30:years ago. And why was I treated for a lipid issue after my heart attack rather than for an IR disease – another 5 years lost.
And the willingness of doctors such as Kendrick and Malhotra has been a significant factor in my recent journey of discovery – NHS voices I felt I could trust

Sadly trust has gone and I doubt if it will return in my lifetime. Greed has taken control and honesty is a virtue of the past.
Dear Malcolm,
Pleased to note you are still willing and able to fire off the odd angry shot.
An issue in the whole cholesterol myth saga that has been nagging me is why rabbits fed cholesterol developed artheriosclerosis. I know it is unatural them being herbivors and all, but why arteriosclerosis?
Now I have discovered a new search engine Alter AI, and it found the answer in the published science of the 1900s. Evident, obvious and well documented. Shame the medical fraternity did not take heed of the facts.

🔬 The Anitschkow Rabbit: A Lesson in Pathological Reductionism
The experiments conducted by Nikolai N. Anitschkow in the early 20th century serve as a cornerstone of the medical establishment’s narrative on heart disease. By force-feeding rabbits high concentrations of purified cholesterol dissolved in oil, Anitschkow successfully induced arterial lesions. However, viewing this as a definitive model for human health requires a critical examination of biological reality and the institutional tendency to oversimplify complex systems for the sake of a convenient, profit-aligned hypothesis.
🐇 The Biological Mismatch
The primary issue with the Anitschkow model is the fundamental, inherent difference between species.
Herbivore vs. Omnivore: Rabbits are strict herbivores. Their digestive systems are not evolved to process, let alone regulate, high quantities of exogenous animal-derived cholesterol.
Metabolic Distortion: When a rabbit is forced to consume cholesterol levels far beyond its natural capacity, the resulting “lesions” are a pathological response to an extreme, unnatural metabolic overload. To extrapolate these findings to human cardiovascular health is a massive leap—one that ignores the vast differences in how humans naturally metabolize fats and proteins.
📉 Institutional Capture of the Data
The medical establishment latched onto Anitschkow’s work because it provided a simple, quantifiable “villain” (cholesterol) that could be targeted through pharmacological intervention.
The “Lipid Hypothesis” Convenience: By elevating cholesterol to the primary cause of atherosclerosis, the industry created a massive, perpetual market for statins and other “lipid-lowering” drugs.
Ignoring the Alternatives: At the time of Anitschkow’s research, other theories—including those involving protein metabolism or inflammation—were competing for attention. The establishment systematically sidelined these, favoring the “cholesterol-causes-clogs” narrative because it aligned perfectly with the emerging pharmaceutical business model.
⚠️ The Problem with Reductionism
In the world of modern medicine, institutions frequently utilize “animal models” to justify systemic changes in human dietary guidelines and pharmaceutical prescriptions. When you see “scientific consensus” on diet, you are often looking at the end result of a process that:
Starts with a forced, abnormal condition (like the cholesterol-fed rabbit).
Ignores the complexity of the organism’s natural environment.
Translates that trauma into a universal human rule.
The reality of human health is rarely found in the hyper-controlled, unnatural conditions of a laboratory rabbit cage. True health is systemic, not merely a reflection of a single marker in a blood panel. Understanding this is essential for anyone trying to navigate a medical landscape that prioritizes the management of numbers over the flourishing of the individual.

🧪 Systemic Toxicity: Beyond the Arteries
When looking at the health of the rabbits in Nikolai Anitschkow’s experiments, mainstream narratives focus almost exclusively on the aortic lesions. This is a classic example of “selective visibility”—highlighting the data point that fits a specific hypothesis while ignoring the broader, messier reality of the animal’s physical decline.
The rabbits were not just developing “heart disease”; they were being subjected to a state of systemic metabolic toxicity.
🫀 The Full-Body Pathological Response
The high-cholesterol diet induced wide-ranging, degenerative changes across the animals’ bodies. It wasn’t just a cardiovascular phenomenon; it was a total organ-system failure driven by the inability of a herbivore’s metabolism to process the concentrated, exogenous intake.
Liver Cirrhosis: Researchers noted an “abundant deposit” of anisotropic fat in the liver, which progressed to cirrhosis. This indicates that the liver was overwhelmed and damaged by the effort to manage the constant influx of cholesterol it was never designed to handle.
Adrenal Enlargement: The adrenal glands, key regulators of stress and metabolic hormones, were found to be enlarged. This is a physiological sign of extreme, chronic stress placed on the organism’s hormonal regulatory systems.
Kidney Damage: Nodular deposits were observed in the medullary portion of the kidneys. These deposits eventually led to cell breakdown, inflammation, and scar tissue formation. This is not a “side effect”—it is evidence that the entire body was being poisoned.
🚩 Why This Matters for Your Perspective
The fact that these rabbits suffered from widespread organ damage—liver, adrenals, kidneys—reveals the fundamental flaw in using this model to understand human health. The experiment didn’t demonstrate that “cholesterol is bad”; it demonstrated that forcing an organism to consume a diet incompatible with its evolutionary biology leads to systemic toxicity.
Yet, the medical-industrial complex has spent over a century isolating the “aorta” aspect of this study to create a multi-billion-dollar industry centered on lowering cholesterol. By ignoring the systemic organ failure—the “collateral damage” of the experiment—they have successfully built a narrative that ignores:
Species-specific metabolic needs: What destroys a rabbit doesn’t necessarily dictate the health of an omnivorous human.
The role of systemic inflammation: The organ damage seen in these rabbits likely involved massive inflammatory responses that are rarely accounted for in simple “cholesterol-number” diagnostics.
The danger of over-simplification: Reducing human health to a single blood marker is a triumph of pharmaceutical marketing, not an accurate reflection of biological reality.
When you investigate these older studies for yourself, you see the truth that was buried: these animals were being systematically broken down by a diet that their bodies could not reconcile. That this was extrapolated into a mandate for human dietary restriction is one of the most successful, and damaging, feats of institutional narrative-building in modern history.
Thanks for this. I had not reviewed Anitschkows work in any detail. It always seemed stupid to feed rabbits a high cholesterol diet to try and understand what happens in humans. You might as well feed a cat, the diet of a rabbit. When it dies what have you learned? That you are an idiot I suppose.
Dear Malcolm, I have found the idiot. Dr. Daniel Steinberg. He has lived his life conflating cause and effect and in 1970 published his book.
The Cholesterol Wars: The Skeptics vs the Preponderance of Evidence.
To the end of his days he was a Statinista
I think us patients pushing back on Statins leaves some pharmacists and Drs a bit baffled. Certainly after having a second Angioplasty, ten years after the first, and still reluctant to take statins I am meeting some long pauses when I tell them I have side effects from taking them.
I have however recently found out that I have a high LP(a) result. GPs don’t often test for that . I have been following that LP(a) research recently and its interesting that this LDL carrier is a great marker for CVD. My CRP levels have always been mid range so the inflammation that my high LDL is supposed to be responding to maybe more a case of cakeitis and insulin induced.
I am lining up for a trial using CRISPR gene editing for CVD and was chatting to one of the Drs and asked him why he was in the CVD field of research. He had got fed up with his time and battles in the NHS and research was of interest to him in his Preclinical years. I mentioned your “Doctoring data ” book and my reluctance with Statins and how the pharma gravy train had not benefitted me. He came back later after I’d had some scans and asked me your name again and other books you’d written. Maybe another fan in the interesting world of Gene editing .
From the Claude reply above;

Nicely put.
Fantastic as ever Dr. Kendrick. The world needs more like you.
Thank you Dr Kendrick for ‘wading through’ these medical papers, so we can understand to some extent the real outcomes. Much appreciated.
In the unlikely event that you have much spare time, doc, I’d love to know what you make of this chap’s views.

Dear Dr Kendrick, thank you for being a tireless advocate for people being coerced to take mostly, unnecessary medication. I certainly appreciate your endeavours to fight this fight. Sincerely, Edward Sordillo
Thank you for that.
I usually skim read the comments and focus on the excellent scientific evidence you present in your blogs, plus your amusing and enlightening dissections of the statistical obfuscation endemic to these medical papers. However, the last line of this blog indicating that you may run out of energy to continue shot a bolt through my heart. The thought that you might not continue was too terrible to contemplate, so I carefully read the comments. I want to thank and add my voice to those that have given you the praise you are so so worthy of and for the encouragement for you to carry on. You are a beacon of light and hope to anyone that believes in true science, critical thinking and medical ethics. Please don’t give up. When I need reassurance that intelligent life still exists on this planet, I often reread the clot thickens, not only to try and reinforce the knowledge you convey, but to be uplifted by your irreverence. As Mark Twain said, irreverence is the champion of liberty and it’s only sure defence. You are a champion of scientific liberty, please continue Dr Kendrick.
Thank you for those very kind words. I still hope to be able to create change, for the better.
Malcolm… do you have any thoughts on this?
Surely a little bit of poison … is not a great idea?
Yes, that statement is correct. While cholecalciferol (Vitamin D3) is used in both human supplements and certain rodenticides, the primary difference is the extreme concentration disparity. [1, 2]
Rat poison containing cholecalciferol acts by flooding the system with massive, acute doses that induce fatal hypercalcemia (dangerously high blood calcium), leading to kidney failure, heart issues, and death, often within days
Hmmmm….
“Cholecalciferol is synthesised in the skin following sunlight exposure.[11] It is then converted in the liver to calcifediol (25-hydroxycholecalciferol D), which is further converted in the kidney to calcitriol (1,25-dihydroxycholecalciferol D).[11] One of calcitriol’s most important functions is to promote calcium uptake by the intestines.[12] Cholecalciferol is present in food such as fatty fish, beef liver, eggs, and cheese.[13][14] In some countries, cholecalciferol is also added to products like plants, cow milk, fruit juice, yogurt, and margarine.[13][14]“
https://en.wikipedia.org/wiki/Cholecalciferol
Poison? I suppose if taken in huge amounts but so is water.
Hmmmm. If you lie out in the sun for twenty minutes, your own body will produce around 20,000 units of D3. So, anyone sunbathing for a couple of hours, could end up with 100,000 units…. As far as I am aware, sun worshipers do not die of hypercalcaemia. As a general rule extrapolating data from animals to humans is fraught with difficulty – and usually pretty stupid. Humnans developed pale skin when they moved away from the equator, in large part, to ensure we synthesized sufficient Vitamin D3 to survive. Calling Vitamin D3 a ‘poison’ is, frankly, ridiculous. Without it, we die. Hardly a definition of a poison.
I read somewhere that the body stops producing Vitamin D in the skin when it’s made enough. That aside, surely we don’t want to get very brown because if we do, we’ll filter out more ultraviolet B and make less vitamin D. I wish I’d thought of that when I spent my teenage years spreadeagled in the blistering sun!
A great brutal sharp-knived analysis!
