CI = confidence interval, ITT = Intention-to-Treat, PP = Per-Protocol.
381patients were originally recruited to the SSG&PM arm, 386 to the SSG arm.
Treatment effect: difference in efficacy between SSG and SSG & PM combination treatment, percent scale with exact binomial 95% CI.
p-value from likelihood ratio test comparing binomial regression models with and without treatment.
p-value from likelihood ratio test comparing binomial regression models with and without factor of interest, after adjustment for treatment allocation.
Complete-case analysis: patients with missing outcome data excluded from analysis.
Worst-case analysis: missing outcomes assumed to be treatment failures.
