Stata : Rr mantel heanzel

[Jade Mio]

I have SMR results by lauching this command : strate maxexpo_ardbis, per(100000) smr(taux_esto)
and i want to have the RR of mantel Haenzel, rr which measures the tendency of increase or decrease of the SMRs according to the classes of the variable maxexpo_ardbis.
Do you know which command i have to lauch for that ?
Thank you so much for your return,
Kind regards,

If you have a cohort study you can use - cs case exposed, by(groupvar) - for that matter.

This is just to underline that the correct spelling is Mantel Haenszel.

Jade, if I understand your problem correctly, you don't need a Mantel-Haenszel test.
It seems to me that you want to test whether there is a (increasing or decreasing) trend in the SMRs across levels of a categorical variable (maxexpo_ardbis).

This test can be found on page 96 of Breslow and Day, Statistical Methods in Cancer Research Volume II: The Design and Analysis of Cohort Studies, IARC Scientific Publication No. 82 freely available at

Alternatively, you can use a Poisson regression model.

Thank you so much for your returns.
In fact I have to have the correct command : Do I have to write : strate maxexpo_ardbis, per(100000) smr(taux_esto) cs case?(variable DCD) exposed? (which variable in my case)? by(maxexpo_ardbis)

Because I have a mortality base of data with several lines per subject (one line by year of follow up with the last line with the status DCD yes or not)
Thank you a lot,
