I am looking to calculate the adjusted mean difference in heart rate by treatment groups (alloc) - this is a binary 0/1 variable, 0=placebo, 1=intervention. I have performed a regress command with finalhr as the dependent variable, i.alloc as the predictor, and adjusted for covariates basehr x y and z. finalhr had to be log-transformed so i used eform() to antiolog coefficients (not sure if this is correct either)

Final code looks like regress finalhr i.alloc basehr x y z

The regress runs well and satisfies assumptions, but I would like to estimate the adjusted mean difference in heart rate, by treatment group.

I tried -margins r.alloc, atmeans- but I don't believe this worked (it may have worked and I may be wrong).

Any help on how to estimate this adjusted mean difference would be much appreciated. Apologies if the answer is something easy, I have very little experience in statistics and with a deadline fast approaching, my internet research has not got me far.

Thanks.
