Obstructive sleep apnoea and quality of life in Ehlers-Danlos syndrome: A parallel cohort study, 2017, Gaisl et al.

[Jonathan Edwards]

The study population was predominantly of Caucasian ethnicity (98.5%) and 82% female.

This is a major red flag. EDS should have equal sex ratio or in some cases male predominance.
Recruitment online is also a red flag.

Sorry, but I cannot get excited about the relevance of any of this.
