Albumin binding above 99% is the whole reason weekly dosing works, and it is also why the trough matters more than the peak.

Agreed, and subgroup analyses deserve particular suspicion. With enough subgroups something is significant by chance, and pre-registered subgroups are a different animal from ones found afterwards.

Coming at maria_elpaso’s question from a different direction. Read four things before the headline number. The population, because trial populations are selected and supported in ways that real cohorts are not. The comparator, because "better than placebo" and "better than the current standard" are different claims and get reported identically. The primary endpoint as pre-registered, because a secondary endpoint promoted after the fact is a hypothesis rather than a finding. And the completion rate, because a large effect in the half of participants who finished is a different result from a large effect in everybody enrolled.

One concrete data point for the thread. Practical: whatever you change, write down the date and the reason. In three months the reason is what you will have forgotten, and the reason is what makes the record worth having.

Correct me if the detail matters more than I have assumed.

One thing that is still open after maria_elpaso’s answer:

How would you tell the difference between that and the alternative explanation?

Filing a mild objection. Mild because I might be wrong; an objection because nobody has addressed the case that does not fit. I think the framing smuggles in the conclusion. Ask it the other way round and the obvious answer reverses, which usually means the question is doing the work.
