ADVERSE EVENTS, SYPHILIS, SECONDARY
The primary outcome was the number of alters who returned photograph-verified syphilis testing results per index, including both facility-based tests and self-tests, over a three-month period. The verification process was conducted by a research assistant by checking the uploaded test result against the result report card using a standard verification protocol (shown in Appendices pp. 6–7). Secondary outcomes included the proportion of first-time syphilis testing among participants, proportion of testers with a positive syphilis testing result, and adverse events during the delivery procedures in each arm during the trial. The secondary outcomes were assessed based on returned syphilis testing result photographs or self-reported data from alter survey. We also report the total economic cost, cost per person tested, and cost per person managed for syphilis in each arm. The costs were collected from a healthcare provider perspective and reported in 2021 US dollars.
