Unfortunately, I've seen hints that some in medicine aren't as impressed with the results and implications of the 2 day CPET as we are, and as we think others should be. Not very often, but it makes me wonder what docs really think that they won't speak about, 'behind closed doors,' so to speak.
The only evidence I can offer regarding this is people who claim to be doctors and offer comments in public, in this case on news articles. So of course from the get-go we know that we can't prove they actually are doctors, though one can usually tell at least if they speak with enough knowledge that we can reasonably presume that they are. An example was on the most recent NPR piece from a week or two ago, that Miriam Tucker wrote about the NIH. First someone who either claims to be a doctor or speaks authoritatively about medicine states that CPET testing hasn't been replicated. They were corrected, then it becomes clear they made a mistake and were referring to PET scans, not CPET tests. Still, concerns about this were dismissed as 'pseudoscientific.' PEM is characterized as a 'crypto diagnosis.' Non-specific, a 'meaningless' symptom.
Another poster claiming to be a doctor asks derisively about controls vs patients in CPET testing, claims it's utterly inadequate and just plain inappropriate to use in CFS, and ends up asking how this could be considered objective evidence in a subjective symptom syndrome it was not designed to be used in. PR's own
@ahimsa debated this person. The next complaint was the size of the study, it was suggested that--the Keller paper? Can't recall. That it should be considered low-quality evidence. Claims made of cherry-picking, sampling bias, and that there were/are issues with the statistical analysis. And more criticism followed.
I've seen this for awhile now. Whenever we see something that seems to be presented as fairly rock-solid evidence that conveys scientifically that which we feel we know about this, it seems that it's only a matter of time before someone comes along to knock it down, and to do so in a way that employs medical knowledge and authority in a way that sometimes seems above our pay grade--and without expert knowledge, it's not always a good idea to keep arguing. At least, from the point of view that once you get to a certain point, it seems unlikely that you're going to change any minds, which surely has to be an important goal. And that's not a knock on anyone who does take on people like this, who I don't really consider trolls, not if they are actually arguing the merits of the science. Besides, that's how science is supposed to work, or so we're told: evidence should be able to withstand this sort of scrutiny.
A little different was the guy on the Atlantic articles recently who kept going on about how his wife's a neurologist and claimed that all the top neurologists in this country view CFS as psychiatric. I don't really doubt that statement. That guy was more trollish, but it doesn't mean he was misrepresenting anyone's position. And I've seen other examples of people claiming medical knowledge--and they seemed to know what they're talking about--doubting everything from the Rituximab studies, to the IOM report, you name it. Does it make sense to dwell on negative comments made in public? Of course not. But we can tell ourselves the CPET is objective evidence until we're blue in the face, but that doesn't necessarily make it so, even if that seems like a pretty good case. It's like continuing to repeat the stuff about 'male pattern baldness' for which there never seems to be any firm evidence, or recycling riffs on quotes from people like Wessely that may or may not actually exist, or are far out of context if they ever actually did, at least to the extent anyone can prove. I am interested in what doctors actually think behind closed doors, and in my experience these doubting Thomases are more significant than we'd care to acknowledge, especially given the entirely reasonable suggestion that they are trolls who are best ignored.
I think we can spot a troll who deserves to be ignored. But when someone starts reducing what we view as our best evidence to a big pile of nothing, I don't see anything wrong with paying attention. They're not alone.
