RCT analysis
Our complete case intention-to-treat analysis was not determined prior to trial implementation. We analysed harm types (relationships, well-being, pressure/persuasion to test) based on trial arm (nBT, BT, nRT, RT). Responses to questions regarding relationship harm, well-being harm and pressure to test were tabulated over numbers who responded to each question by trial arm. Participants reporting false positive results in 2-week, 3-month, regular and exit surveys were tabulated over all who reported an HIVST result or using HIVST during trial follow-up (including kits not sourced from SELPHI). To avoid double counting, participants from BT subsequently randomised a second time contributed only to nRT and RT endpoints. Stata V.16.1 was used for analysis.
