Worth stating the units and the reference range whenever you post a number here.

Thank you — that is the clearest version of this I have read, and I have read a lot of them.

From the other side of the consultation, briefly. 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.

Moderator note: two posts asking for a source have been merged into one. Please search the thread before asking again. Report rather than reply if it drifts again.

Adding the part of the answer the thread has not reached. Start from the measurement rather than the conclusion. Almost every disagreement here turns out to be two people measuring different things and comparing the numbers anyway.

One concrete data point for the thread. The boring version of this is the one that works, and the boring version is: measure a baseline, change one variable, wait, measure again under the same conditions. Nobody wants that answer and it is still the answer.
