proc stdrate (rate ratios?)

andrewp_82 — Mon, 13 Oct 2014 03:34:51 GMT

I am trying to calculate the Incidence rate ratio (IRR) using proc stdrate. In particular I want to obtain the following statistics:

Number of observations and the expected number of observations in the exposed group ;
Number of observations and the expected number of observations in the non-exposed group ;
IRR and the 95% CI.

I have gone through the proc stdrate user’s guide however I have been unable to work out how to extract these statistics.

The code I have used is:

proc stdrate data = exposed_reduced refdata = control_reduced

method = indirect

stat=rate

effect=ratio

;

population event=observed_total total=pyear_total ;

reference event=observed_total total=pyear_total ;

strata post_strata rank_strata agegrp_cancer_1 year_cancer / effect ;

run;

Any guidance would be much appreciated.

what at are you expecting this proc to do? My understanding was this was for calculating age-sex standardized rates for example or maybe I'm missing something.
