Dear Stata users,

I am trying to compare the differences in means on a list of variables
between participant and comparison group. After obtaining the difference
for each variable, I want to run a t-test and test for significance.

You should look up the -foreach command

foreach var of varlist a b c d etc{
ttest `var', by(group)
}
