Hi all, I’m writing this message to ask about SAS procedures or syntax to get the cumulative incidence, absolute risk reduction and relative risk (please see below for an example) by years of follow-up i.e at 4 years, 8 years, 12 years and 16 years, etc. I have used PROC FREQ to get the overall all-cause mortality cumulative incidence by treatment group, the absolute risk reduction and relative risk for the overall, age < 65, age >= 65. PROC FREQ is used assuming there is no censoring to get the estimates for cumulative incidence, absolute risk and relative risk. However, I’m having trouble finding the cumulative incidence, absolute risk reduction and relative risk at 4 years, 8 years, 12 years and 16 years. I was just wondering if which SAS PROC or macro to use to get the numbers Please HELP!!! Thank you very very much! Warriortv
