There is a second half to this that has not been said yet. 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.

One concrete data point for the thread. Keep the original post as written when you update it, and add the correction underneath. An edited-away mistake is invisible to the next person who makes it.

That is the short version; the long version is somebody else's post.

One thing that is still open after Dr.LeslieOBGYN’s answer:

Closing the loop on my own question.

For the archive: it took about six weeks rather than the two I expected, and the difference between those two numbers was the whole of my problem.
