Dear Peggy,

egen totalmg=rowtotal(mg_1-mg_108)

should work.

Dear List,

I need to find the total mg of a treatment received for each subject. I
have mg of treatment drug as variables mg_1 for the first dose received
through mg_108 for the last dose received. I would normally just create
a variable, e.g. gen totalmg= mg_1 + mg_2 to find the total, but since I
have 108 doses to sum, I am wondering if there is a more efficient way
to create the totalmg?

Thanks,
pc
