Firthlogit - How to report RR?

[Natallia Lapitskaya]

I am running a -firthlogit (suggested here in Forum by Clyde) - to calculate if the Intervention influence the prevalence of the medication use (Randomized study, 185 persons in intervention group, 183 persons in the control group; intervention variable is r_treat), PersonWithn_Tricycl3==1 if person gets the tricyclic andtidepressants at 90 day followup, PersonWithn_Tricycl1==1 if person gets the tricyclic andtidepressants at baseline, same for many other medications.
I got question to adjust for the baseline medication.
As an example for the tricyclic --baseline tricyclic antidepressants a perfect predictor of the tricyclic outcome.

firthlogit PersonWithn_Tricycl3 ib1.r_treat ib2.PersonWithn_Tricycl1
firthlogit, or

I was asked to report Risk Ratios istedet for Odds Ratios, but cannot get it working with -firthlogit-.


All the suggestions how to get displayed RR with

firthlogit
