Abstract

In their response to Geraghty, the PACE investigators state that they have “repeatedly addressed” the various methodological concerns raised about the trial.

While this is true, these responses have repeatedly failed to provide satisfactory explanations for the trial’s very serious flaws.

This commentary examines how the current response once again demonstrates the ways in which the investigators avoid acknowledging the obvious problems with PACE and offer non-answers instead—arguments that fall apart quickly under scrutiny.

(This is a commnentary on: White PD, Chalder T, Sharpe M, et al. Response to the editorial by Dr Geraghty. Journal of Health Psychology. 2017;22(9):1113-1117. doi:10.1177/1359105316688953 )

 

The table of contents of the Journal of Health Psychology's 2017 Special Issue on the PACE trial is linked in the S4ME Science Library.

I thought it's worthwhile to post some of these articles on the forum so they're easier to find for people new to the topic.

I also found it worth to re-read them in the light of some individuals' and Royal Colleges' weird reaction to the new NICE guidelines on ME/CFS.

From the response by the PACE team:

"We stand firmly by the findings of the PACE trial, which, along with other studies, provide patients, healthcare professionals, and commissioners with the best evidence that both CBT and GET are safe and effective treatments for this chronic and disabling illness. Others share this view (National Institute for Health and Clinical Excellence, 2011; NHS Choices, 2011; The Lancet, 2011, 2015).

"These findings are good news for patients who, in our experience, just want to get better. Of course, we need further trials, not only of CBT and GET but also other treatments. To this end, we hope that editorials such as that by Dr Geraghty do not discourage others from doing such research."

The references to those "who share this view" are:

1) National Institute for Health and Clinical Excellence, 2011
= Review of Clinical Guideline (CG53) – Chronic fatigue syndrome/myalgic encephalomyelitis (or encephalopathy): Diagnosis and management of chronic fatigue syndrome, myalgic encephalomyelitis (or encephalopathy) in adults and children. Available at: https://www.nice.org.uk/guidance/cg53/evidence/review-decision-2011-546258781

The link now refers to the updated guideline: "This guideline has been updated and replaced by NICE guideline NG206."

2) NHS Choices, 2011
= NHS Choices (2011) Therapies ‘moderately improve’ CFS. Available at: http://www.nhs.uk/news/2011/02February/Pages/therapies-moderately-improve-CFS.aspx

Link doesn't work for me. Perhaps works only within the UK?

The other two references are editorials from The Lancet, the journal that published the PACE trial. No author name so presumably by the editor, Richard Horton?

3) The Lancet (2011) Editorial: Patients’ power and PACE. The Lancet 377(9780): 1808.
DOI:https://doi.org/10.1016/S0140-6736(11)60696-X

Link 2 does not work in the UK.

 

Uh, never noticed that. Still they keep saying the old trope about how it's because we don't want to get better. They can say one thing and its opposite and no one but us even care. Whatever is useful at the time.

But then that's why they invented the trope of activists who aren't patients. Or whatever, always what's convenient at the time.

 

Just having a look through some of this earlier work.

I love this bit, though I'm sure it's been noted elsewhere in the forum archives. As it's logically impossible to rate any differently to t0 at t0, it reduces down to "no patient can be regarded as recovered at entry because they weren't at entry." Or more simply: "no patient can be regarded as recovered at entry."
