The distinction that resolves most of these threads is between what is true on average and what is true for one person.

Coming at DeniseRN_TPA’s question from a different direction. 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.

Following on from DeniseRN_TPA — and this may be the naive question:

What would you measure differently if you were starting again?

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. The counter-case has not been addressed. Somebody upthread described the situation that does not fit, and the thread moved on rather than engaging with it, which is the failure mode this board is supposed to avoid.

No disagreement, though it depends on where somebody is starting from, and this thread has been assuming a starting point nobody stated.
