Randomization and Masking
RECRUITMENT
We randomized 16 health facilities in a 1:1 ratio to intervention or control group. Randomization was stratified by health facility size (3 strata). All facilities were randomized at the same time using block randomization with a block size of 2 within each stratum. Treatment assignment was known to participants, clinicians, evaluators, and data analysts. Participant recruitment occurred after randomization. See eMethods in
