ANOVA repeated measures

Struggeling to find the right command in STATA for this repeated measures.

I am going to to a repeated measures of bloodpressure testing for treatment , adjusted for gender, i am also going to add a term for interaction between treatment and gender.

I have tried several but i get error, i get a output if i dont have any interaction term, but not if i have the interaction term betweetn gender and treatment. What am i doing wrong?


Less is more. Stay pure. Stay poor.
I don't use STATA, but was wondering if your were using a term gender*treatment or if you created the interaction term out side of the model and were introducing it as say X3?

It might also help the STATA people if you cut-n-paste your error message.
