They have previously described this cohort in another paper:

Ha, that's my guess too. We'll find out someday!
Though there are a few others around the same p-value of .02, so there might be some other interesting ones too. ¿Si?

Myalgic Encephalomyelitis (ME/CFS) Awareness - ‘What Was I Made For?'
YouTube has been recommending a bunch of music by people with ME/CFS and I'm surprised by how much of it is really good. So I'm making a thread to compile songs about ME/CFS or music videos that are focused on ME/CFS.

I wish they would have tested more nights. REM looks to have mostly recovered by night 7, so far all we know, it was only really low on a single night immediately after running. Total sleep time does seem to still be a little low at night 7 (6.7 hrs) compared to night 21 (8.0 hrs).
I calculated the actual time in each stage using the percentages from Table 2. Minutes of slow wave sleep was modestly higher (11.8%) at night 1 compared to night 7. But minutes of REM was much lower (-63.7%) on night 1 compared to night 7.
It looks like the main effect of the marathons was...
That would be my first guess on seeing that data.
This similar statement from the text suggests they don't necessarily think REM decreased because it isn't necessary, but that slow wave sleep increased because it is important in recovery:
Edit: But the fact that total sleep time decreased...
It seems like they're just inferring that based on the person having less REM after these marathons.

Video on the ME/CFS Research Foundation Youtube channel. It's a really catchy song. The title translates to "What we want". And here is a Claude translation of the auto-generated lyrics:

Impressive looking results.
Only 1 dropout out of 31 in the agomelatine group.
I wonder if it'd be better to individually assign participants to placebo or active, instead of assigning them to "group A" or "group B", because for the group method, if a clinician is able to guess a single...
