On the subject in the title: Reverse causation in a cohort study of weight and outcome Working notes rather than a conclusion.

Posting a small dataset on reverse causation. It is mine, it is uncontrolled, and the method is stated so it can be discounted appropriately.

What I would like is not agreement but a second dataset collected by someone with no stake in mine. If one exists I would rather read it than argue for this one.

Reverse causation is worth one more sentence than it usually gets, and the sentence is the one about how the number was arrived at.

Adding the measurement that post #2 says would settle it.

Trying to state the reverse causation position in a way that someone who disagrees would recognise as fair, because I do not think the version in this thread passes that test.

Small methodological point on reverse causation: repeating a measurement is cheap and resolves most of what is being argued about here at no cost to anyone.

r.ilunga, post #3: Adding the measurement that post #2 says would settle it. Trying to state the reverse causation position in a way that someone who disagrees would recognise as fair, because I do not think the version in this thread passes that test. Go to post

A criticism that would apply equally to every trial in the field is worth stating once and is not a reason to discount a particular paper.
