Try 'sttocc' (convert survival-time data to case-control data). See

Hi All

We have a study we meaure demographic data and an binary outcome (and a

then we want to select the cases (that easy) and matching controls (mathec
on the demographic variable) for specific expensive blod sample analysis
(alisa find the matching controls in at nested case-control study)

has anyone writen a program for this task?
or is the coding itself very easy?
