RE: st: FW: how to caculate proportional mortality ratios
Thank you for Svend the response (below) to my adjusted proportional mortality ratio question.
I re-read this Rothman & Greenland section you suggested, and agreed with you that treating the PMR as a case control study may be the way to go. I used the cci command to and obtained the crude PMR, but I still haven't figured out how to calculate an age adjusted proportional mortality ratio in Stata.
Thanks again,
Lara

Sorry for a mundane question. I need to calculate age-standardized
proportional mortality ratios (PMRs). I have a poisson dataset and I'm
calculating SMRs using both poisson & negative binomial regression
commands. I also want to calculate PMRs to check my SMRs. I need age
adjusted PMRs. I can not find anything in the Stata manuals or online
that offers Stata code for PMRs. I want to caluclate many PMRs and
Proportional cancer mortality ratios across many different cancer sites,
to do this in Excel would take a long time to hand enter my data.
Is this possible to do in Stata?

I'm not sure. But Rothman and Greenland (Modern Epidemiology, p 76)
recommend to think of PMR studies as case-control studies. Would it be
reasonable, then, to do a stratified analysis with -cc- or a logistic
regression?
