The honest answer is that the effect is real, the magnitude is contested, and the individual variation is larger than either.

True, with the qualification that this is a self-selected group. The people for whom it did not work post less, and that shapes everything we think we know.

Agreed, and the size of the effect matters as much as its existence.

This is exactly what I could not find anywhere else. Adding it to my notes with a link back to this thread.

I do not accept the framing. The question has been narrowed to the version that has a tidy answer, and the part that was dropped is the part the OP actually asked about.

One concrete data point for the thread. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.
