@EMcCra2 @drphyto @GeoffSchuler @edgeben ...I never said it was proof of anything. It explains why systematic reviews are proof.
@EMcCra2 @drphyto @GeoffSchuler @edgeben You would only expect an equal number of studies for and against if there was no effect either way.

@drphyto@GeoffSchuler@edgeben Actually the number of studies in meaningless; it's the strength of the studies that's important. -

@drphyto@GeoffSchuler@edgeben So for example 1 high-quality RCT of 1500 people is more useful than a small case-control of 50.
