Clinical perspective, offered as context rather than as advice. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

Adding the part of the answer the thread has not reached. Most of what circulates confidently in this community traces back to one summary of one study, and the qualifier was dropped somewhere in the third retelling.

The figures, for anyone assembling their own picture. If you are comparing against somebody else’s result, check that you are comparing the same measurement taken the same way. Most of the apparent contradictions in these threads dissolve at that step.

Closing the loop on my own question.

Resolved, and the thing that resolved it was the least interesting suggestion in the thread. Writing that down for the next person who wants the interesting answer.
