    This open access rejoinder officially came out today. I thought I would highlight it in its own thread.

    Well argued response, Tom and Carolyn. :)
    I am sure that even Professor Sharpe will see the light! ;)

    Brutal response. I'd throw in the towel if I was them.

    Wait a second, you're not supposed to say that!

    Such a clearly-written reply. Well done :)

    That does read as they adjusted the thresholds to meet their needs. And we should remember that the Wilshire definition was their definition before they saw the data.

    So why make the changes, and then defend them so ferociously, if they are of no significance?

    So the changes do make a significant difference? Make up your minds. :rolleyes:

    The whole damn point of PACE was to test those previous results and clinical experience. The PACE authors themselves called PACE "definitive". That was the basis on which they pitched PACE to the funding and approval bodies.

    Also, clinical opinion is the lowest ranking in the formal evidence hierarchy. It is meaningless in the context of a (supposedly) rigorous clinical trial.

    I read it again and find myself wanting to quote loads of it here just to be able to say YES!!! each time. Since that would just produce a whole lot more for you to read, I'll just say one big

    YES!!!

    to the whole paper. And huge thanks to @Carolyn Wilshire and @Tom Kindlon for writing such a superb rebuttal of Sharpe's nonsense. No wonder he's so rattled he's blocking people who link to this paper on Twitter.

    I don't see how scientists can survive saying this in the long term:

    We prefer the definitions of recovery we used to those used by Wilshire et al. as they give absolute rates more consistent both with the literature, and with our clinical experience.

    Nor can I. I was astonished when I read it - couldn't believe they could so blatantly make such an unscientific statement. Like a criminal admitting their crime openly, but too stupid to realise what they'd done.

    I loved the Wilshire and Kindlon response to it:

    Simon Wessely had stated something similar in a comment under @Jrehmeyer article in statnews (edit, in 2016):
    https://www.statnews.com/2016/09/21/chronic-fatigue-syndrome-pace-trial/comment-page-6/#comments
    (page 2 of comments)

    It was really puzzling that he didn't realise how such a statement was revealing of their conception of "science".
    But it was in an internet comment.
    Now Sharpe et al. are claiming that in an academic journal. How can they not see that this is a non scientific statement?

    So, we have the perfect storm:

    Risk of expectation bias is high in unblinded trials.
    Risk is expected to be higher for ME, because of the nature of the relevant endpoints.
    Risk is expected to be exceptionally high for CBT since cognitive bias is part of the treatment.
    Risk is expected to be off scale if the investigators do not understand the purpose of a scientific experiment - to challenge expectations.
