Randomization and masking
SECONDARY
Randomization was open‐label, with variable size blocks, without stratification. The study statistician generated the random allocation sequence using Statistical Analysis Software (SAS) Programming, by blocks in a 2:1 ratio for the intervention (secondary distribution of HIVST) and SOC. Sequentially numbered envelopes corresponding to the random allocation sequence were used to implement randomization immediately upon written consent. Participants and providers were unblinded to arm assignments, but investigators were blinded until the study end.
