I'm glad to hear about the diagnostic criteria being used.
But I see no clarification regarding the two-day exercise. If this is not in the form of a maximal CPET, I predict a lot of waffle regarding patients holding back, blah blah blah. And yes, some moderate ME patients would do a two-day maximal CPET - I would be willing to, for quality research, to help put an end to that ME denialist BS.
Their FMD "control" group is still a huge problem in every way imaginable. Those patients need their own quality research, with healthy controls. Comparing two very controversial groups like ME/CFS and FMD with each other seems like a shockingly bad idea at this stage, with no legitimate purpose or potential merit, not to mention added expense. It also looks like they are starting with the assumption that FMD and ME/CFS are basically the same thing, which is an extremely bad sign.
And who are the actual ME/CFS researchers who will be part of the team for this study, and not just providing a little bit of background data? Why is the project being led by someone who knows nothing about ME/CFS? Who else is on the team?
These things need to be clarified and/or changed.
