Re: st: Breslow-Day test
I have a problem when performing my meta-analysis: Instead of Q-Statistic, I would like to use the option “BRESLOW’ to perform the Breslow-Day test for homogeneity of the odds ratio. However, my “METAN” command is not working.
categorical data
The Breslow-Day test of interaction does exactly this, with the null hypothesis that all strata have the same odds ratio, which need not be equal to one. This test is implemented in the EpiR R package. The Breslow-Day p value of .14 means we can make this
Cochran–Mantel–Haenszel (CMH) test
Breslow-Day Test shows signficant p-value (<0.5) for the data considered Test for assumptions One of the main assumption of CMH test is that the association between two categorical test variables are significant different for various levels of control variable.

Association analysis
–bd combines this procedure with the Breslow-Day test of the hypothesis that all the strata share a single odds ratio. Both of these commands write results to plink .cmh . Permutation testing based on the CMH (default) or Breslow-Day (when –bd’s ‘ perm-bd ‘ modifier is present; this always uses adaptive permutation) statistic is supported, as well as CMH-based variant set testing.

The Breslow‐Day test was used to assess whether the difference between active and sham groups depends on the perceived assignment (P = .911). The high P value of this analysis indicates that the interaction is not significant and thus the difference between the active and sham groups is not affected by the perceived assignment.
