Look - in general I don't disagree with you, and I also agree with that Klimas quote. But first, we're talking about a sub-group here, second mold doesn't appear to be causative, and third, Sick Building Syndrome is not the same thing as Chronic Fatigue Syndrome. There might be some symptom overlap, but afaik they are distinct entities.
I don't mean this in a "thread police" way, but this is a thread on the Lerner study and the results he found with antivirals. So I don't think diverting it to a discussion of mold is really appropriate. I'm sure we all wish there were researchers looking at every possible aspect of CFS under the sun, but unfortunately that isn't happening, and that is also not the focus of this study.
This study is also not so much a research study as it is a clinical study. That's how I view it, at least. Yes, there are some flaws in it. But I think in some respect we have to take it on its face - by which I don't mean not to criticize the methodology, etc. - but not fault it for what it's not and what it's not trying to be. I think his results are interesting, they might not represent a "cure," but only a functional improvement, or however you want to categorize it, but it's one more part of the picture that at least someone is reporting on. If XMRV pans out, who knows how something like this might dovetail with XMRV to actually provide the "cure" we all want. don't throw out the baby with the bathwater, especially just because it's not the gender baby you wanted.
