Good Morning,

I am a relatively new STATA15 user. I need some help obtaining the confidence interval and p-value output after executing the stmh command. e.g:

Code:
stmh age_at_start, c(2,1)


         failure _d:  ltfup_status
   analysis time _t:  date_of_nextapp/365.25
  enter on or after:  time art_start_date
                 id:  artnumber

Maximum likelihood estimate of the rate ratio
  comparing age_at_artstart2==2 vs. age_at_artstart2==1

RR estimate, and lower and upper 95% confidence limits

        ----------------------------------------------------------
             RR       chi2        P>chi2      [95% Conf. Interval]
        ----------------------------------------------------------
          2.041     143.33        0.0000         1.812      2.300
        ----------------------------------------------------------
I am only able to get the RR value using the return list command. Your help will be greatly appreciated.

Thanks,

Paul
