Oh, and thanks very much @Jonathan Edwards for the planned letter! Excellent.
Actually, didn't the decision to replace the review only get made under K SW's watch?

What it may not convey is why people within Cochrane and outside should be so deeply ‘shocked’. The international healthcare community needs to be aware of the implications of the statement made by Hilda Bastian (2025) on her blog, Absolutely Maybe, given as the title of this letter.
re-writing ... re-write ... sub-standard
Having authored a review
Chalmers dismissed my concerns at the time, but it is now very clear that they were well-founded.
Whoever was responsible for the decision to block the project from early on needs to be named and shamed.
No, she didn't think it was substandard when she allowed it to be published in 2019. One of the IAG and I met with her in July 2019 and he begged her not to publish it. She told us it was too late and the deal was done. As we found out from correspondence obtained through FOI, the deal was done in June 2019 https://acrobat.adobe.com/id/urn:aaid:sc:EU:314a94ec-b56c-48fa-b8f8-890b87a960c6and the subsequent Editor in Chief, Karla Soare-Weiser.
I had sight of another version of the review, never published,
Whoever was responsible for the decision to block the project needs to be named and shamed. Otherwise, Cochrane’s reputation is worthless.
I think this language is too intense for something you want BMJ to publish.
I think it might be better to say that those who blocked it should be required to publicly put their case for it, with their names attached.It might be, but at least half the point of submitting this is to expose the BMJ editorial office to the arguments. I am not in favour of pussyfooting. Last time I sent in something about as critical it was published. Thee might be another wording. I will have a think.
Have you been able to identify where the pressure was coming from? Was it just Larun and her boss at that stage, or had the Wessely, White, Glasziou, and other BPS crew piled in too?She was even weaker than David Tovey on this, and that is saying something. She totally caved to pressure and has refused to engage with anyone on it. She needs to resign.
Do you know when the decision to make the new review was made (which K S-W announced as being necessary because the methodology of the Larun review was outdated, etc)?No, she didn't think it was substandard when she allowed it to be published in 2019.

Yes, do we know anything about Karla S-W that might indicate why she is so supportive of the Larun et al review? Does she have connections with any BPS proponents or insurance companies? Does she have any experience of ME/CFS?Have you been able to identify where the pressure was coming from? Was it just Larun and her boss at that stage, or had the Wessely, White, Glasziou, and other BPS crew piled in too?
She's a psychiatrist. She will know Paul Garner very well. She's co-authored stuff with him eg https://www.bmj.com/content/354/bmj.i3507Yes, do we know anything about Karla S-W that might indicate why she is so supportive of the Larun et al review?

There's a guy called Andy Oxman, well known in Cochrane, who was at the NIPH at the time, who is also very close with Iain Chalmers. Chalmers is famously hostile to people with ME. He turned very frosty with me in 2019 when he realised I was an ally! Anyway, Oxman was the one that suggested Gordon Guyatt as an arbitrator allowing the ridiculous torturing of the text to be able to say that exercise probably helps with fatigue. Although GG said they should clarify it doesn't have an important effect, the authors chose to ignore himHave you been able to identify where the pressure was coming from?

anyone has the text of guyatts reply?Although GG said they should clarify it doesn't have an important effect, the authors chose to ignore him
Think the important-effect comment was from this PDF of FOI'd correspondence:anyone has the text of guyatts reply?
Just to clarify, the judgment of moderate is contingent on rating certainty on a non-zero effect.
This implies that the authors do not claim an important effect and should avoid any language that claims an important effect. It would be reasonable to require in limitations that they highlight that they have not established an important effect.
Details should remain on point, but would it be worth mentioning that a similar thing happened with the NICE guideline? As a pattern of behavior, one that is especially appalling given that the same ideologues have for years alleged, implied and even stated outright that we were not only doing that, but very successful at it.“Advocates of the intervention launched a full-on bid to try to stop the project. “

Newly identified studies can change the conclusion of a review. If they have not been included, this threatens the validity of the review, and, at worst, means the review could mislead. For patients and other healthcare consumers, this means that care and policy development might not be fully informed by the latest research; furthermore, researchers could be misled and carry out research in areas where no further research is actually needed.1 Thus, there are clear benefits to updating reviews, rather than duplicating the entire process as new evidence emerges or new methods develop. Indeed, there is probably added value to updating a review, because this will include taking into account comments and criticisms, and adoption of new methods in an iterative process.2 3 4 5 6
I guess we can say that in the case of the relabelling of the 2019 review as 2024 without changing a word, the expectation was that the update would indeed influence the credibility of it sufficiently to justify the effort. Whether it does or not remains to be seen.The decision needs to take into account whether the review addresses a current question, uses valid methods, and is well conducted; and whether there are new relevant methods, new studies, or new information on existing included studies. Given this information, the agency, editors, or authors need to judge whether the update will influence the review findings or credibility sufficiently to justify the effort in updating it.
The PUGs panel defined an update of a systematic review as a new edition of a published systematic review with changes that can include new data, new methods, or new analyses to the previous edition. This expands on a previous definition of a systematic review update.10 An update asks a similar question with regard to the participants, intervention, comparisons, and outcomes (PICO) and has similar objectives; thus it has similar inclusion criteria. These inclusion criteria can be modified in the light of developments within the topic area with new interventions, new standards, and new approaches. Updates will include a new search for potentially relevant studies and incorporate any eligible studies or data; and adjust the findings and conclusions as appropriate. Box 1 provides some examples.
They say here that if a review has vague inclusion criteria (yes), poorly articulated outcomes (probably, ignored objective outcomes), inappropriate methods (absolutely, included subjective evidence from unblinded trials unsupported by objective evidence), then updating should not proceed, and it is better to start again.Did the review use valid methods and was it well conducted?
If the question is current and clearly defined, the systematic review needs to have used valid methods and be well conducted. If the review has vague inclusion criteria, poorly articulated outcomes, or inappropriate methods, then updating should not proceed. If the question is current, and the review has been cited or used, then it might be appropriate to simply start with a new protocol. The appraisal should take into account the methods in use when the review was done.
Loving the car window point. I’m being childish now in admitting it gave me fond memories of The Inbetweeners famous habit of shouting a certain nick name out of car windows at people waiting for a bus. But variations on that wouldn’t get publishedMy concern is that when people read websites or magazines, they skim, and if your title doesn't summarise what you say in your letter, a huge proportion of the readership is unlikely to ever get the message - they'll simply skip over your letter and keep going. It's the nature of how people read this kind of thing that it will be a real win if they read the first paragraph, let alone the rest.
“Advocates of the intervention launched a full-on bid to try to stop the project" is opaque, because it doesn't say what project you're talking about. I'd go for the single thing you'd shout out of your car window about the situation if you passed a medical friend walking along the pavement. Something like, 'Cochrane's failures over its ME/CFS review severely damage its reputation' (there will be better phrases, but this is a quick illustration).
And then I think the first sentence needs to say what has actually happened, for those who didn't read the article. At the moment you start with, 'The News article by Jacqui Wise (2025) today gives a fair account of the disgraceful behaviour at Cochrane over the planned re-writing of the Systematic Review on Exercise Therapy for ME/CFS.' But how about, 'The News article by Jacqui Wise (2025) today gives a fair account of the disgraceful behaviour at Cochrane in abandoning the planned re-writing of its poor-quality Systematic Review on Exercise Therapy for ME/CFS, which risks harm to patients.
Even if that was all that anyone read, you would have successfully stuck the boot into Cochrane, as it deserves.
