Dear STATA lister, it might be simple question...

I have cohort followed over 12 months. Time points have 2 variables:
   visit: coded after the number of weeks on treatmnet:
0,2,4,8,12,16,20,24,36 & 52 (patients expected to come on these weeks)
otherwise coded 999 if unexpected visit.
   week: showing the exact week number patient came to clinic.

I am trying to generate variable with value=1 to select patients who
came at all visits (mentioned above), with intention to identify
patients who did not come to the expected appointments.


Any tips about it?

Thank you in advance and best regards
ziad
