Dear Statalists, I try to combine two diagnoses variables to one, for patients that mostly only have 1 diagnosis for seizures etiology, but a minority has 2 etiologies/diagnoses, I can't figure out how to make only one variable. Concat doesn't work, I tried to merge 1:1 id , any idea? Thanks for your help!
