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…

That is right for the common case. Whether it is right for the case being asked about depends on a detail that has not been given.

Right, and one flattering data point from a group buy is not consistency.

Genuinely useful, thank you. I had the facts and not the framework. Sending this to two other people who asked me the same thing last week.

Careful with the causal language. Two things moving together in a period when five things changed is not a mechanism, and stating it as one makes the thread less useful to somebody reading it later.

Adding the numbers, since they settle part of this. Give anything pharmacological four weeks before you judge it, and give anything measured weekly a four-point rolling average before you call it a trend.

Moderator note: good thread. Keeping it here rather than moving it, because the question is general enough to be useful. No action needed from anybody.
