Graded exercise therapy compared to activity management for paediatric [CFS/ME]: pragmatic randomized controlled trial, 2024, Gaunt, Crawley et al.

It's interesting too that there's a marked difference at baseline between the GET and AM groups who attended 2 or less sessions. The AM group slightly better than the participants as a whole, while GET group is a lot worse. Maybe just due to chance, but could be a different dynamic in not continuing to attend between the two groups. The GET group too sick to attend, while the AM a bit better, possibly recovering and what was offered under AM was similar to what they were doing anyway.
