The study isn't bad, but there is a potential red flag, namely these authors are fishing in the data retrospectively for associations... Now if the authors preregistered their hypotheses and mentioned which hypotheses were tested and found to have null results, their results could be interpreted...

I can't say I've ever experienced a "golden hour" or anything short term resembling remission...

Makes you wonder why the actual authors didn't bother to read it to make sure there were no errors in the publication.

Simon Wessely's "biomedical" research was really designed and conducted by colleagues/grad students, such as Anthony Cleare who did do some novel neuroendocrinology work, but unfortunately didn't find anything particularly interesting.

I have discussed the directionality of symptoms before, namely cognitive effort leads to cognitive PEM, whereas a sufficient amount of physical exercise leads to both physical "crash" and cognitive "crash". The sensory issues only come when everything is really severe - only when the brain is...

¯\_(ツ)_/¯

More GIGO. The problem is the lack of prospective studies. What you get is selection bias - eg only people who believe in the association actually submit their questionnaires to the researchers.

I agree. It is hard to have an "absolute measure" of recovery though, as there is no true basis for a clear demarcation

The concept of "recovery" is always sketchy when you have been ill for so long and no real point of comparison to know what that is.

Agreed. It's too easy to be seen to be doing the right things with regard to "involvement", while you're actually stacking the deck against any substantial changes being made.

That is Esther Crawley's clinic. http://www.ruh.nhs.uk/patients/services/clinical_depts/paediatric_cfs_me/info.asp This shows clear selection biases in the CFS patients that does not necessarily exist in the other samples, namely referal to a clinic that focuses on psychological treatments...

I'd say no it is not. It is hard to say, but population based studies have found similar (often higher, but that could be due to methodological difference) prevalence in South American and Asian populations, as well as in non-white populations in the USA and UK.

Okay, thanks for letting us know. It seems quite unprofessional that there was no communication throughout the process, including no announcement that a committee has been selected.

The sad part is he's not going to recover using their programme...

It's an interesting hypothesis, but unfortunately, it's also almost certainly wrong.

I don't understand why they're talking about "conversion" of chronic fatigue into CFS. The demarcation is purely diagnostic - whether there is another medical condition that is presumed to cause the symptoms or the symptoms have lasted more than 6 months, to meet the CFS criteria. The...

The results provided in the abstract aren't the ones of interests - it is not peak cardiac output or VO2Peak that we are interested in, because it's possible that patients simply worked harder on the second test and achieved a higher heart rate. We're interested in stroke volume and O2 pulse...
