Hi there, is there any way to compare 2 odds ratios? I have two tests
that are supposed to detect a disease presence. So for each test, I can
compute an odds ratio. My problem is how can I compare the 2 tests by
testing whether the 2 odds ratios are the same? Note both tests were
performed on the same set of patients

Cochran-Mantel-Haenszel test (where test type is considered a stratum)?
Log-linear modelling?
