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.
Adding the numbers, since they settle part of this. Give anything pharmacological four weeks before you judge it, and give anything measured weekly a four-point rolling average before you call it a trend.
Correct me if the detail matters more than I have assumed.

This is where I part company with the consensus forming above. I think the framing smuggles in the conclusion. Ask it the other way round and the obvious answer reverses, which usually means the question is doing the work.
Moderator note: leaving this open. It is being argued well and the disagreement is the useful part. Report rather than reply if it drifts again.
