Hi there
Could anyone please suggest a formal test for comparing whether the effect of a risk factor is significantly stronger for one outcome than for another when using Cox regression?
For example, to test whether the (hypothetical) effect of eating red meat is significantly stronger for colon cancer (HR 2.2, 2.0-2.4) than for rectal cancer (HR 1.8, 95%CI 1.6-2.0).
