Hi everyone,
I'm planning to match cases and controls based on age (within 3 years), gender, index date (within 3 years – index date is date of incident treatment prescription). I read about 'psmatch2' and other Stata commands. However, it seems to me that they match with the exact value given in the variable. I'm not sure how can I match within certain interval for a given variable in the list of matching variables.
