WebAug 26, 2024 · $\begingroup$ The Mantel-Haenszel test for odds ratio isn't the same test as the Cochran-Mantel-Haenszel test the OP asked about. It is the case that MH test will return the same result as the logistic regression described (p value for the interaction). It sounds like this is what the OP is looking for.

WebDescription. The Cochran-Mantel-Haenszel test computes an odds ratio taking into account a confounding factor. The test creates a series of two-by-two tables showing the … We consider a binary outcome variable such as case status (e.g. lung cancer) and a binary predictor such as treatment status (e.g. smoking). The observations are grouped in strata. The stratified data are summarized in a series of 2 × 2 contingency tables, one for each stratum. The i-th such contingency table is: The common odds-ratio of the K contingency tables is defined as:
