Dear STATA lister

I have VL level per patient per clinic visit (visits are 4,8,12,16,20,24,36&52)

I did score every patient for how many times s/he got high VL (0.yes,
1.no), by this code:
egen thighvl=total(highvl),by(studyid), if select==1

i am trying to find a way to have a list of patients who had thighvl>2
including week24, i.e. there should be at least 1 highvl=1 before
visit 24 and highvl=1 by visit 24.

Any tips?


Thank you and best regards
ziad
