I have a database of somes patients. Each patient has 3 or 4 drugs or more. Each drug has to be divided in 2 or 3 categories such as off-label, unlicensed, or licensed. Each drug may be licensed and off-label for age at the same time.
My question is that what is the best way to create these variables in Epi Info for an easy analysis after???
Thank you in advance to help me.
