Hello,
I am trying to calculate age-standardized incidence rates of TIA events per 1000 population per year per age statum and overall.
I am using the following file as weights:
This my stata code:
dstdize tia popn age, by(ckd) using("..../standard population.dta")
and this is my output:
I have two questions:
1. Unfortunately the event rate here is for a 5 year period and I need to calculate per 1000 population per year so I understand that I can x1000 but do I then divide by 5? How do I then calculate the 95% CIs?
2. Is there any code that will report the 95% CI for the adjusted incidence rates per strata (i.e. per age group) instead of only for the summary adjusted estimate?
Thanks for your help!
