Dear EpiData lister, I am entering longitudinal data into EpiData, is it possible to have a variable 'visit' that will have new number every time I enter new record for the same patient? Then it will start from beginning with number when i am entering new patient? example below
id visit -- ----- 1001 1 1001 2 1001 3 1001 4 1001 5 1002 1 1002 2 1002 3 1003 1 1003 2 1004 1 1004 2 1004 3 etc..
Thank you in advance and best regards ziad
