Question:
Can anyone easily point me towards a link to the relevant review which was current in 2011?
This is a link to the version history of the Cochrane CFS exercise review
https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD003200.pub9/information#versionTable
The 2004 version by Edmunds at al was the most recent in 2011, see

Given the Larun et al (whichever of the arbitrary dates you want to attach) is largely based on the PACE data what we are seeing here is the ongoing battle of Wessely supporters trying to save PACE. The Cochrane review, now with a misleading 2024 publication date, is just fancy window dressing to escape the enormous controversy over PACE whilst still pushing its false conclusions.
One caveat is that PACE is not really the trial that is driving the effect in the meta-analysis (it often found lower effects than the meta-analysis estimates). It's mainly the 2001 Powell et al. study that inflated the effects.yeah, this seems like what's happening.
It's mainly the 2001 Powell et al. study that inflated the effects.
No, I think that was Wallman 2004. The Powell 2001 trial used the same intervention as FITNET.Powell wasn't even a GET study, though it called itself that. It was a pacing study designed to see if people could increase without breaching their PEM threshold.
If an error, we expect that the incorrect date will be swiftly corrected.

How a review published in 2019 became a review published in 2024
24 Dec 2024
2019 or 2024?
The observant among you will have noticed that we are now calling for the Cochrane 2019/2024 review (rather than the 2019 review) to be withdrawn. The reason for the change is astonishing.
Back in 2019, the Cochrane Editor-in-Chief Dr Karla Soares-Weiser published the Larun et al review, but noted that, even after a series of amendments, it was
"still based on a research question and a set of methods from 2002, and reflects evidence from studies that applied definitions of ME/CFS from the 1990s". She noted that Cochrane had decided that "a new approach to the publication of evidence in this area is needed" and announced the new review development process on this "globally important health topic". Since then, a global pandemic has resulted in a huge increase in the number of people meeting ME/CFS diagnostic criteria, surely making it an even more important topic.
As we reported in the last update, Cochrane announced that that replacement review that has been in the works for some five years would now not go ahead. The carefully selected writing team finished a protocol nearly two years ago and delivered it to Cochrane for approval. The carefully selected Independent Advisory Group was poised to provide comments on the protocol, but was never given it. Cochrane abandoned the new review process, citing "insufficient new research in the field" and "a lack of resources to oversee the work". We'll have a closer look at those reasons in the next update.
On 19 December 2024 Cochrane added a new editorial note to the 2019 review, informing readers that
" Cochrane is ceasing the production of a full update of this Cochrane review. A pilot project for engaging interest holders in the development of this Cochrane review was initiated on 2 October 2019 (see Editorial Note below) and has now been disbanded. Cochrane maintains its decision to publish this Cochrane review in 2019."
To be clear, the 2019 review has not been changed, it has not been updated.
The only things that have changed about the 2019 review are the addition of that editorial note about the abandonment of the new review process...
... and the citation for the 2019 review.
"Larun L, Brurberg KG, Odgaard-Jensen J, Price JR. Exercise therapy for chronic fatigue syndrome. Cochrane Database of Systematic Reviews 2024"
Yes, it is now a review with a 2024 publication date. It is not yet clear if the 2024 citation date is just an error, or if it was done deliberately. If an error, we expect that the incorrect date will be swiftly corrected.
The effect of a 2024 publication date is to make the review seem much more relevant than it otherwise would. The unchanged 2019 review now appears from the citation to be a fresh new up-to-date review, and indeed it has been shared on social media, probably mistakenly, as a new review. Uninformed readers will assume that it represents a distillation of the latest knowledge using the best methods, and that criticisms of the 2019 version have been fully addressed. The review, with its 2024 date, appears newer than the 2021 NICE Guidelines and Evidence Review which unequivocally warned that people with ME/CFS should not be treated Graded Exercise Therapy.
A 2024 publication date is particularly misleading as the 2019 version of the review was actually the result of a series of amendments over several years. The literature search was undertaken in 2014 and so the review contains no source material more recent than the 2011 PACE study report.
Surely this situation where an unchanged review is relabelled with a publication date 5 years after the actual publication date is preposterous and will not be allowed to stand?
Our best wishes to the supporters of this campaign
As a new year approaches, we thank you for your support and hope that 2025 brings better health, much happiness and exciting new developments in the understanding of ME/CFS.
So will Cochrane now include this means of turning an out of date review into a new one in their new training manual ?... and the citation for the 2019 review.
"Larun L, Brurberg KG, Odgaard-Jensen J, Price JR. Exercise therapy for chronic fatigue syndrome. Cochrane Database of Systematic Reviews 2024"
Yes, it is now a review with a 2024 publication date.

- As new studies are completed, the results of reviews may become out of date and thereby provide misleading information to decision makers.
- Cochrane Reviews should be assessed periodically to determine whether an update is needed. The decision to update should be based on the continuing importance of the review question to decision makers and the availability of new data or new methods that would have a meaningful impact on the review findings.
- A review update provides an opportunity for the scope, eligibility criteria and methods used in the review to be revised.
- An update should be conducted according to the standards required for any review, with some additional requirements to ensure that any changes are managed appropriately and reported clearly to readers.

...ideologues would still insist that it was a well-designed trial, which seems to be the universal "doesn't matter that this checks every single what-not-to-do box" excuse.....
........Long Covid has proven that this is an indutry-wide crisis, with hundreds of teams independently producing the same garbage pseudoscience, behaving the same way with all criticisms and the same total systemic failure in clinical practice and research alike.
If it wasn't them and PACE, it would be some other group with some other garbage low-quality high-bias handful of trials.
The flaw is in the whole profession, in its institutions and it being driven by secretive policies far more than science.
This is horrendous and misleading. Cochrane will be used to harm Australians and they will continue to be forced to undergo GET despite the harm it causes and the rejection of GET by the UK and the USA. Is there any other disease in which the people with lived experience continuously and consistently report severe harm caused by a management regime and their experience is ignored?

I thought the following recent comment on the petition was worth copying here:
In 2019 Cochrane in effect acknowledged the chasm between the group of researchers advocating exercise as a curative treatment for ME and the majority of people with ME and their advocates and promised us a means of input into the new exercise review. Five years on Cochrane, despite some 80 ME and Long Covid patient organisations and very nearly 14,000 individual petition signatures, have chosen to backtrack on that commitment and stand firmly in support of an approach to treatment that they know causes harm.
This commenter has identified the core issue that the BPS approach to ME is based on a fundamental denial of the patient experience, a profound contempt for the very people they are meant to be helping, that Cochrane are actively lending their prestige and influence to promote this harmful treatment knowing it will be used in national and local guidelines and service planning as we are seeing in the current new guideline process happening in Australia.
Can someone please clue me up on (with evidential links if possible) exactly who the target audience for a Cochrane Review is designed to be? Obviously researchers but who on the medical frontline treating patients would actually check up on them, or is it just policy makers and management boards?
