From: Impact of a mobile phone-based interactive voice response software on tuberculosis treatment outcomes in Uganda (CFL-TB): a protocol for a randomized controlled trial

Outcomes Measure of outcomes (intervention versus control arm) Statistical analysis
Treatment success Proportion of patients with treatment success at six months. Odds ratio of treatment success Logistic regression, odds ratios
Cure rates Proportion of patients cured of TB; odds ratio of TB cure Logistic regression, odds ratios
Treatment completion Treatment completion rate; odds ratio of treatment completion Logistic regression, odds ratios
Retention in care Hazards of attrition in the intervention versus control; Cumulative attrition at six months Cox’s proportional hazards model, log-rank test
Adherence to TB medicines Mean adherence rates (proportion of TB medicines) Mann-Whitney U test and Poisson regression
Appointment keeping and punctuality Proportion of patients who keep an appointment; Proportion of patients with early, prompt, and late visits Ordered logistic regression
Drug-resistant TB rates Proportion of patients with rifampicin-resistant TB Logistic regression, odds ratios
Call success rates (2,4, and 6 months) Proportion of successful calls t test
