Data from included studies were analysed for the CB DOT and the clinic DOT intervention. If studies additionally included patients undergoing other types of DOT supervision (e.g. DOT provided by private physicians) or SAT, we only included the patients receiving CB DOT or clinic DOT.
The primary outcome was the proportion of patients who were successfully treated; the secondary outcome was the proportion of patients who were lost to follow-up. Meta-analyses were performed for both outcomes.
