Dear all.

Using 

mhodds x y, by(z)

I have analyzed the relation between -x- (0 or 1) and -y- (0 or 1 or 2) in two cohorts (-z-) to get pooled OR and M-H for homogeneity. 
In a review process I am now asked to provide a P for homogeneity by Breslow-Day instead of Mantel-Haenszel testing. Does anyone know if and how this could be calculated by STATA? As -y- is not binary -cc x y, by(z) bd- will not work.

Many thanks in advance,
Berthold
