Randomization design flowchart [17]. HF: health facility; GV: group village; PMTCT: Prevention of Mother to Child Transmission of HIV; bEmOC: basic emergency obstetric care. ^aOne GV consisted of a large number of individuals that used a HF in a different catchment area; a second GV was participating in another maternal and child health project. These GVs were replaced with alternative GVs. ^bEight GVs were selected from a high population HF, which could not be implemented feasibly within one area. Thus, four GVs were eliminated and the PPS sample for this HF was obtained from the remaining four GVs in the HF catchment area
