The authors also use some strong language. They write: Which seems rather inappropriate - it's not like they have any data for or against this...
Looks like a great article. Many thanks to the wonderful Giada Da Ros!
New study: A retrospective observational study of Lyme neuroborreliosis in the southwest of England by Petridou et al. They retrospectively...
Was listening to this 2016 podcast "Everything Herz: 17: Journals: Do we need them?" and they mentioned that in physics and mathematics it is...
But in that case, patients were actively encouraged to interpret and their symptoms differently, so they were like primed to fill in the...
Apologies in advance for being difficult, but I think this helps in understanding things. But how would you test the reliability of an outcome...
I think we fully agree on this Trish, it's just that I would label these problems as issues with trial design (bias) rather than the reliability...
I suppose that short questionnaires that focus on a particular issue (not overall impairment) and don't have large scoring ranges would be better...
Perhaps things would be clearer if you could give an example of an outcome measure that that doesn't have this problem because I still don't seem...
I notice that biorxiv, the preprint server for biology, has added a note saying:
I don't think I agree with this. The problem you sketched is mostly a problem of clinical trial design where you have to control for other factors...
It seems that these are problems of all questionnaires, not only the ones used here (and probably of other outcome measures as well). I suspect...
Yes, but I think that's only if you use the scale in the healthy population and if you look at a patient group such as ME/CFS that you get a crude...
One of the authors of this abstract, Italian researcher Elenka Brenna, has published the following back in 2018: Chronic Fatigue Syndrome...
Thanks for explaining! But isn't that the case then for all questionnaires that add scores to different questions? In my view, it makes sense...
What do you mean with the false assumption that this is linear data they are dealing with?
Some list E-Cronicon as a predatory publisher: https://beallslist.net/
Quite frustrating how the results are reported here. In the methods section the authors report that "the following measures were recorded for the...
Has anyone looked in-depth at cerebral perfusion in ME/CFS? I know there are quite a few studies that have reported this but is it a robust...
We have also made a tutorial video on how to to use Twitter to participate in MEawarenesshour (please don't laugh at the poor quality of the video...
