Accounting for the pair‐matched cluster randomized design [Primary and secondary outcomes were compared between arms with targeted minimum loss‐based estimation, accounting for the dependence of outcomes within clusters and adaptively adjusting for baseline covariates to maximize precision, while preserving Type‐I error control [Within the intervention arm, we also summarized visit coverage and dynamic choice of the intervention components, including prevention product (PrEP, PEP, condoms only or none), location choice (out‐of‐clinic or clinic) and HIV testing (rapid or self‐testing) at baseline, week 24 and week 48.
