The opening post describes the usual case. This is about the unusual one.

Having read the whole STEP 4 thread before replying: the question in the first post has not actually been answered yet, and three of us have answered a nearby one instead.

DKwiatkowski, post #1: On the subject in the title: Journal club: STEP 4 and what a withdrawal design can prove Working notes rather than a conclusion. Session topic: STEP 4 ( JAMA , 2021). Please read it before posting; the discussion is much better when everyone has. The question I would like us to start with is what the trial set out to estimate, rather… Go to post

Thank you for taking the time. That was more work than a reply usually is.

Careful with the language on STEP 4. "Not detected" and "not present" are different findings and the first is a statement about the method.

i.osei, post #5: Picking up post #2: that is the part I would want checked first. 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. Not disagreeing with anyone above, just adding the bit I keep having to look up. Go to post

Post #14 is the version of this I will quote in future. One addition.

Taking STEP 4 seriously for a moment rather than deflecting: the honest position is that the community has observations and no controlled comparison, and those two things support very different sentences.

integrator_trace, post #28: STEP 4 would be much easier to settle if anyone reported the denominator. Almost nobody reports the denominator. Go to post

Critical appraisal template: (1) What did the trial set out to estimate? (2) Could the design answer that question? (3) Was the population sufficiently similar to your population to apply the results? (4) What was the absolute effect, not just the relative one? (5) What are the two strongest criticisms available?

It reads as pedantry until the day it does not.

Post #42 answers the question as asked. The question underneath it is different.

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.

One more caveat and then I will stop qualifying: the sample selected itself.

Post #51 is the version of this I will quote in future. One addition.

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 put a moderate confidence on that and no more.

Everything in post #55 holds. The case it does not cover is the one I have.

Adding a null result on STEP 4. I looked, carefully, and found nothing, and null results deserve posting precisely because they never are.

The confident answers on STEP 4 and the well-sourced answers are not the same answers, which is the most useful thing I have learned reading this category.
