    @Michiel Tack Thanks for doing this.

    I think you will probably have to submit your letter as a manuscript – although you might want to double check that. Technical info for submissions to the journal here: https://www.editorialmanager.com/jobm/default.aspx

    I would recommend getting an ORCHID ID if you have not already got one, as this is a generic ID which is needed to submit a manuscript to any science journal. Not all journals require ORCHID for letters though, and some ask you to register with their own systems too. Be prepared that it may take a couple of hours to get the IDs and fill in all the necessary forms.

    If you’d like me to have a look at the letter, or need any other advice, please feel free to copy me in on any private conversations.

    Thanks, that's exactly what I needed to know.

    You could look through the journal to see how many references letters had. Some journals only allow letters to have 5 references.

    I have never had this issue (i.e. requiring a ORCHID ID). But certainly it does take a while to submit any publication, including a letter.

    I'm sure I needed one for my Lancet letter - as well as having to register with their EES system. Perhaps I only needed to provide my ORCHID ID after the letter was accepted.

    But Dolphin has a lot more experience than me, so I'm clearly wrong about it being needed for all science journals.

    Thanks though I could be out of date.

    I just had a quick look at this, so here are some notes.

    They say a higher IQ is a risk factor for CFS? Was that just from the one study where they assumed low IQ would be a risk factor, found a higher IQ was associated with diagnosis, and then said it was a trivial finding? (They lumped all their references for risk factors together, so it would be a bit of a pain to check).

    It seems like they make a lot of claims based on very tentative data so I'm not going to pull out all the examples (other people have mentioned some earlier in the thread). It's a bit depressing that they're not more cautious with their narrative building, even post PACE-gate.

    "In phase 2 of recruitment, in order to increase recruit-
    ment rates, the threshold for severity was raised to 50%. At
    this level, a person would still experience moderate
    symptoms which would increase following activity. Three
    participants were recruited during this second phase."

    What? So they changed their entry cut-off from 30 to 50 for just three more participants?

    "43 participants (84.3%) met the Oxford criteria for CFS/ME"

    I wonder why the other participants not meet it? That seems odd considering how loose Oxford is, and that this started as an attempt to study those with severe CFS/ME.

    "Correlations

    The results of the correlation analyses can be seen in
    Table 3. In summary, significant associations were found
    between the following variables: stronger fear avoidance
    beliefs were associated with higher levels of fatigue at T1,
    and with worse social adjustment at T1 and T2. Female
    gender was significantly associated with lower levels of
    school attendance at T1 and T2. Similarly, access to
    treatment was associated with lower levels of school
    attendance at T1 and T2."

    But, as @Michiel Tack pointed out, the abstract says:

    "Stronger fear avoidance beliefs at T1 were associated
    with higher fatigue at T2, and with worse social adjustment
    at T1 and T2."

    How can they have got this wrong. Anything here we're missing?

    "As seen in the Table A1 in the supplementary material, the
    addition of time as a covariate did not alter the findings of
    the multiple regression analyses except that the variables
    fear avoidance and gender were not significant predictors
    of T2 social adjustment."

    That seems like a fairly important alteration to a finding emphasised in the paper's abstract.

    I can't believe I did anything to help! I'm sure there is an imposter going around pretending to be me, because I have no recollection of half the things I am supposed to have done.
