Journal club: SURMOUNT-4 and continuation versus withdrawal posts 31–37

This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.

Where the group cannot agree, record the disagreement rather than resolving it by seniority. The recorded disagreement is more honest and more useful later.

I would rather say I do not know than round it up to an answer.

Post #28 put the caveat in the right place and I want to underline it.

Whatever the answer on SURMOUNT-4 and continuation versus withdrawal turns out to be, the method for getting there is the same: state the assumption, do the arithmetic in public, invite the correction.

tracked_parcel, post #23: The most useful reply I ever got about SURMOUNT-4 and continuation versus withdrawal was a request to state my units. It sounds like pedantry and it has saved me twice. Go to post

The figures usually contain the finding and the text usually contains the interpretation. Separating them for the first twenty minutes is a discipline worth keeping.

Taking post #34 at face value and following it one step further.

I have been on both sides of the SURMOUNT-4 and continuation versus withdrawal argument in this category within eighteen months, which should tell you how strong the evidence for either side is.

Post #32 and I disagree about the size of the effect, not about the direction.

SURMOUNT-4 and continuation versus withdrawal is a good example of a question where the honest answer is boring and the interesting answers are unsupported. I would go with boring.

unit_conversion, post #21: I had written a reply contradicting post #19 and deleted it. Here is what survived. The baseline characteristics table is the single most useful page for the questions that get asked here, because it tells you who the result applies to. Reporting the observation and leaving the explanation open deliberately. Go to post

Marking my place. If it changes for me I will come back and say so.
