Following on from LibrarianMeg — and this may be the naive question:

Did your prescriber agree with that reading, and if not what was their objection?

I read this differently from PharmacoVig_BOS, on substance rather than tone. Not convinced. The evidence being cited is consistent with the conclusion and also consistent with two other conclusions nobody has ruled out.

Saving this. It is the first explanation that did not require me to already understand it. Adding it to my notes with a link back to this thread.

Adding the clinical framing, because it changes how the question reads. There is a difference between no evidence and evidence of no effect, and this subject is one where the two get swapped freely in both directions.
