Ah I see Vermeulen 2010 showed this difference, but several of the papers with a "calculated" SpO2 in the mepedia table dont actually report anything in the text about it (e.g. Hodges, Davenport, Nelson, van Campen) so hard to say if it was different from controls. 1/
As far as I can tell only two studies have shown SpO2 decreases more in MECFS than controls, and at least four studies that apparently had that data but didnt report it, which makes me think the difference wasn't replicated in those studies.
I've just never heard blood oxygen levels referred to as VO2 since they're completely different metrics, so I'm guessing a mistake, since I would think VO2 would be the stronger finding to focus on. But yeah, it'll be interesting to see what future studies show about SpO2 as well.
(I assume the other studies I mentioned tested SpO2 and put it in supplementary files, otherwise I'm not sure what the MEpedia calculated figures are based on. And AFAICT the figures in the table are not compared to controls anyway.)
