Statins in the over 75s

A rapid response was published in the BMJ here.

Executive Summary

– A study was published in The Lancet, which was reported worldwide as “giving statins to people over the age of 75 could save thousands of lives.”

– This claim came from a press conference to launch the Lancet Paper, where a lead author, Colin Baigent, was quoted as saying: “Only a third of the 5.5 million over 75s in the UK take statins and up to 8000 deaths per year could be prevented if all took them.”

– This is false. It relies upon evidence in the over 75s for both deaths and primary prevention (people who do not already have heart disease) and neither was found.

– Figure 5 in The Lancet paper confirmed that the Rate Ratio (RR) for vascular deaths for over 75s was not statistically significant. Nor was it for those aged 70-75 for that matter. Even with the attempt to achieve a significant result, by excluding trials that failed to show benefit of statins, the RR for vascular deaths for over 75s was not statistically significant.

– Figure 4 in The Lancet paper confirmed that the RR for major vascular events for over 75s without vascular disease was not statistically significant. Nor was it for those aged 70-75 for that matter.

– This article was reported worldwide as ‘statins can save thousands of lives in the over 75s’. No statistical significance was achieved for deaths or primary prevention in this age group. The falsehoods need to be corrected.


The Cholesterol Treatment Trialists’ (CTT) Collaboration has been quiet for a while, so a major publication in The Lancet (the favoured journal for CTT publications) was perhaps overdue. One duly appeared on 1st February 2019. It was entitled “Efficacy and safety of statin therapy in older people: a meta-analysis of individual participant data from 28 randomised controlled trials” (Ref 1).

It attracted much media attention on both sides of the pond. CNN reported “After years of uncertainty, study finds statins can benefit all ages, including those over 75” (Ref 2). The UK Times reported “Giving statins to all older people could save 8,000 lives every year” (Ref 3). The story took up the front page of the UK Express newspaper “Statins really do save lives” (Ref 4).


As I shared in this post (Ref 5), “the CTSU is the Oxford Clinical Trial Service Unit. Where this ends and the CTT (Cholesterol Treatment Trialists) Collaboration begins or where CTT ends and where Sir Professor Rory Collins and Colin Baigent and co. begin or end, I know not. One gets the impression that the web between the parties is not intended to be clear.”

It is important to read that post for context to this note. That post went through the attacks made by Collins on authors of two articles published in the BMJ and attacks on the BMJ itself. Before this happened (in the summer of 2014), I had already identified approximately £115 million of funding from drug companies to the CTSU. In the disclosures that were required as part of the full BMJ independent investigation, it emerged that the full extent of the funding from pharma to the CTSU was beyond £268 million. That was back in 2014; it can only have increased since then.

The CTSU is also the group that, despite requests from journalists and the BMJ, has refused to share information from their statin trials, so that it can be independently examined. The CTSU has also refused to share data about serious adverse events, so we have the outrageous situation that data exist that could inform prescription practices and the holders of these data refuse to share them.

The lives saved claim

The claim about lives saved was remarkably consistent across the media reports:

But scientists said up to 8,000 lives could be saved annually in the UK alone if everyone over the age of 75 received statin therapy.” (The Express)

Everyone over the age of 75 should be considered for cholesterol-lowering statins, experts have urged, after an analysis found up to 8,000 lives a year could be saved.” (The Times)

Researchers said up to 8,000 deaths a year could be prevented if GPs simply prescribed drugs costing pennies a day.” (The Telegraph) (Ref 6).

Up to 8,000 pensioners a year are needlessly dying of heart disease because they are not being given statins, leading experts warn.” (The Daily Mail) (Ref 7).

The 8,000 lives saved claim came from a press conference, which was held on January 30th to launch the paper. The press conference was reported in a BMJ article, which quoted Colin Baigent as saying “Only a third of the 5.5 million over 75s in the UK take statins and up to 8000 deaths per year could be prevented if all took them” (Ref 8).

The problem with the 8,000 lives saved/deaths prevented claim is that it cannot be supported from evidence in the paper.

The study

The study published on 1st February was a meta-analysis of trials for which the CTSU holds data. The objective of the study was set out in the introduction: “We aimed to do a meta-analysis of data from all large statin trials to compare the effects of statin therapy at different ages and explore the effects of statin therapy among older individuals.” The specific age of interest in the abstract of the paper and throughout the paper and in media coverage was the over 75 age group.

The paper reported that, from the available data on 186,854 people, 14,483 people were over the age of 75. Of these 14,483 people, 55% had a history of heart disease of some kind (so 45% didn’t). The average total cholesterol for the over 75s was 5.1 mmol/l and the average LDL cholesterol for this group was 3.2 mmol/l. The abstract (summary) of the paper reported that “Overall, statin therapy or a more intensive statin regimen produced a 21% (RR 0·79, 95% CI 0·77–0·81) proportional reduction in major vascular events per 1·0 mmol/L reduction in LDL cholesterol” (Ref 9).

There are five Figures in the paper. The only one that looked at deaths was Figure 5. It reported that the rate ratio (RR) for statins (achieving a 1 mmol/l reduction in LDL) vs. the control group in the over 75s was 0.95 (95% CI 0.83–1.07). That includes the line of no effect (1.0) and thus could have happened by chance and thus was not statistically significant. Interestingly the result for the age group 70-75 was also not statistically significant. Neither of these can be reported as a finding therefore.

The CTT personnel even re-calculated the RRs after leaving out four trials where “statin therapy had not been shown to be effective.” Yes – really – ponder on that for a second. Even leaving out four trials that didn’t show support for statins, they still could not achieve a statistically significant result in the over 75 age group.

All the reports in the media that “up to 8,000 lives a year could be saved”, with reference to over 75s (or over 70s without the fudge) are false.

The evidence for cholesterol lowering in the elderly

I knew to doubt this claim as soon as I saw it because I worked on a paper published in 2016 with Dr Uffe Ravnskov as the lead author (Ref 10). The paper was called “Lack of an association or an inverse association between low-density-lipoprotein cholesterol and mortality in the elderly: a systematic review.“ I spent several weeks doing the data extraction with Uffe and cross checking each other’s tables. I withdrew my name from the paper before publication because the correct (PRISMA) systematic review/meta-analysis methodology was not followed. This did not impact the results and, having seen the data first hand, the conclusion is robust. The conclusion was: “High LDL-C is inversely associated with mortality in most people over 60years.” i.e. high LDL-cholesterol is associated with lower deaths in most people over 60.

I also knew to doubt the “lives saved” claim because statin patient leaflets caution against statin use in the over 70s. Here’s an extract from the Lipitor leaflet (the most prescribed statin) (Ref 11):

What about events?
Even if the death claims are lies, what about the claimed reduction in events? The newspapers reported that, “for every 10,000 people aged 78, who take statins, but have no history of cardiovascular problems, 80 heart attacks or strokes would be prevented every year.”

This came from the press release (Ref 12) and the Lancet paper itself. Both identically reported “In the primary prevention setting…” [i.e. in individuals with no known history of vascular disease], “Reducing those risks by a fifth with a 1.0 mmol/L LDL cholesterol reduction would prevent first major vascular events from occurring each year in 50 individuals aged 63 years and 80 individuals aged 78 years per 10,000 people treated.”

This is also false.

– Figure 1 reported effects on major vascular events by age. This is the Figure that gave the top level claim in the abstract of the paper as shared in “The Study” section above: “Overall, statin therapy or a more intensive statin regimen produced a 21% (RR 0·79, 95% CI 0·77–0·81) proportional reduction in major vascular events per 1·0 mmol/L reduction in LDL cholesterol.”

– Figure 2 reported major vascular events by age and by type of trial (heart failure trials vs. dialysis trials vs. other trials).

– Figure 3 reported major vascular events by age and by type of event (coronary event, stroke etc).

– Figure 4 reported major vascular events by age and by previous vascular disease. There was no statistically significant difference between the statin group and the control group in people over 75 (or in the 70-75 age group). Benefit in those who have “no history of cardiovascular problems” cannot be claimed, therefore.

Serious Adverse Effects

Notwithstanding that no benefit can be claimed for those without previous vascular disease – and hence there will not be 80 fewer events per 10,000 78-year olds given statins – there will be serious adverse events in those people if they take statins.

The Number Needed to Treat (NNT) is the important measure to examine. The web site for this is Frustratingly, these numbers seem to change every time I look at the page (I suspect that there is intense pressure from drug companies for these figures to be ‘re-visited’). Currently, the NNT numbers advise that 1 in 10 people who take statins without known heart disease will be harmed by muscle damage and 1 in 50 will be harmed by developing (type 2) diabetes (Ref 13). So, for every 10,000 people given statins, 1,000 are likely to develop muscle damage and 200 are likely to develop (type 2) diabetes. For no benefit in heart disease.

The Daily Mail article reported Colin Baigent as having said that “a number of misleading studies – which he branded ‘fake news’ – had created confusion over the effectiveness and side-effects of statins among doctors and patients.”

The only fake news that I can find is coming from Baigent himself.

  • Hi Zoe,

    I just joined your blog after seeing several of your youtube videos.
    I am interested in finding out if there is evidence that statins will help for a 75-year-old with a previous heart attack.

    Thanks for any help,

    • Hi Richard
      Figure 4 is the one to look at for previous vascular disease. The bottom part of the figure shows the results for participants with vascular disease. This reported a RR of 0.85 (0.73-0.98) for the over 75s. This was statistically significant – for a 1 mmol reduction in LDL. We don’t know what the difference would be if someone did not experience this drop (see this

      However this is relative risk. The absolute risk difference is in brackets – 6 vs 6.8% and this would need to be weighed up against the known risk of side effects – especially the 1 in 50 risk of type 2 diabetes that is commonly reported.

      Best wishes – Zoe

  • Hello Dr Harcombe.

    I have enjoyed your presentations at PHC conferences.

    I am not a Mail (Daily, on Sunday or online) reader, but I was tipped off about Calman’s vicious attack.

    I thought I would see how the author gained his medical expertise. The boy has done well for a former frock salesman. I was surprised at how even handed his reporting really is when I discovered his earlier contribution to an article praising CAC scanning as a useful tool to prevent inappropriate over-prescribing of statins. I posted this in the PHC Ambassadors Face book group – see below.

    By the way, my cholesterol doubled when I stopped taking statins – to 5! My latest total cholesterol was 5 with HDL of 1.3 and my GP’s receptionist has told me that my records will be noted to show that I refused statins.

    I had a suspected CV event in 2016, post-statin cessation, and they concluded that I had not had one, that my coronary arteries had narrowed consistent with my age but flow was not restricted. They did not insert stents but prescribed bisoprolol and aspirin and discharged me. I later persuaded my nephrologist to de-prescribe the bisoprolol. One cardiologist said my change to LCHF/IF had probably helped my heart and another said ‘Fat is good’ when I admitted to my dangerous LCHF habit. The LVH in my obese years has resolved to a normal size with minimal impairment.

    My wife recently had a newly introduced health check for old people who aren’t ill. When the HCA warned that she would have to see a doctor about statins if her cholesterol was high, Lynne emphatically replied NO! before the end of the sentence. TC turned out to be 6.4 with HDL 1.6. Lynne ignored the letter telling her she was ‘eligible for statins’.

    Thanks for your enlightening and entertaining writings.

    Best wishes,


    My Facebook post:

    After reading Barney Calman’s intemperate rant attacking ‘statin denier propaganda’, I searched the internet for any articles giving a balanced view on the potential risks associated with over-prescribing statins (aside from the well-referenced writings of Drs Harcombe, Kendrick, Malhotra etc) and I found an earlier article in which was a more balanced report of fears about over-prescribing statins, in more moderate language and including politely reported contrary opinions. See the interesting personal experience reported in Heart Test 3 by Health Editor BARNEY CALMAN. He obviously has no personal experience of possible adverse effects of statins because his coronary artery calcification scan convinced him that he needn’t take statins.

    I wonder what has changed his mind so radically? It can’t be scientific bias, because his education and earlier employment seem to be centred on fashion and promotions.

    • Hi John
      Thanks so much for your lovely message and research!
      Best wishes – Zoe
      p.s. say hi at the next PHC!

  • Dears Hi, the absolute truth is from NNT in all trials, also to mention the main pathophysiology drivers in elderly people are inflammaging and immunosenesence. Our effort has as epicenter to reverse if is possible these drivers , nice rest of the time, George

  • I heard a wonderful phrase apropos something completely different which we Galileans should use freely against those who claim we are spreading fake news.

    We cannot trust a group that is marking its own homework.

    BTW I have submitted a Rapid Response to the BMJ on its news piece about the Lancet paper as well as writing to Richard Horton calling for said paper to be retracted. It’s interesting that several authors have openly accused the Oxford group and others of fraud but I am not aware that any of them have yet been sued for libel…

  • I think this is an example of a claim that, even taken at face value, as if it were true, reveals serious problems.
    Imagine if giving a statin (or two or 3, I’m not sure how often they should be taken) every day to 10,000 people in some group could prevent 80 events.
    That means that 9920 people in every 10000 – 99.2% – have just taken a drug for a whole year for no benefit. Some have lived, I’m guessing many have died in this age group, but the drug has made no difference to them unless it has had side effects.
    This is a waste of resources and doctors and patient’s time and effort. It is not comparable to a vaccine, where for benefit to be conferred on A, B and C may indeed need to take the drug with no effect. It is just a huge waste.
    And what this tells us is, (assuming that statins are still effective) that even within clinically controlled trials, the calculations being used to prescribe statins and dosages are woefully inaccurate – almost useless. They are preventing them being given to the 80 in every 10,000 who would benefit, or even the 200 of whom 80 would benefit, giving a reasonable NNT.
    If you are using your drug like a shot gun you A) don’t know how it works, B) have no idea what causes the disease you are treating.
    And no wonder – statins are prescribed because they lower LDL. But if they are handed out on the basis of LDL levels, they are plainly not going to the right people.
    Even worse is to prescribe them on the basis of age, just because older people are more likely to die. This is missing the point totally.

  • My concern is that the side effects of statins can easily masquerade as something else. In my case, I have a polio leg, and after taking statins for three years, I got severe cramping pains and extra weakness, just in that leg. I was sent to a polio specialist to decide if I had Post Polio Syndrome (PPS). Fortunately I decided to stop my statins temporarily and the problem started to fade away. I actually started and stopped the damn things 3 times before the penny dropped. It took about 9 months to get completely back to normal.

    Obviously I will never take a statin again!

    Over at Dr Kendrick’s site, someone reported that his 80 year old mother was scheduled for a hip replacement, but he persuaded her to stop her statins for a month – just to see. She is now able to enjoy long walks again, and is no longer on the list for a hip replacement!

    I think it should be standard practice to take people off statins for a trial period if they develop any symptoms of this sort – even if another explanation is possible.

  • Simple. They won’t confront their critics so they are very hard to take seriously. Richard Horton wants the matter settled so he hires the “neutral” critic Rory Whatshisname, an arch statinator. Joe Hill wants us to just stop. I don’t personally have an opinion about benefit vs. risk but the above goes to credibility as they say in court.

  • I am 77, a cardiac patient, doing well without statins. When I attempted to use them I always suffered side effects. I have long suspected financial double-dealing in the industry. Color me skeptical when it comes to these studies alleging that statins save lives. Thank you for this analysis!

  • Hi Zoe

    My first post here. I notice they saw a vanishing benefit for all-cause mortality with increasing age, they then recovered their “benefit” when they pulled the data for heart failure and dialysis trials.


    • Hi Rich – yes – but even with this fudge, they still couldn’t get a finding in the over 75s!
      Best wishes – Zoe
