Participants and network
Two‐thirds
Of 37,068 residents who met the inclusion criteria for the HITS study, 15,675 participated and 15,665 were included in the analysis (see Figure It was common for participants to have family members in different households (60.4%, 9468/15,675) and different communities (42.2%, 6613/15,675) (see Table Baseline characteristicsEach community had family connections with almost every other community (see Figure Family connections between communities in HITS study. The top part of the figure is a grid showing the number of family connections within each of the 45 randomization communities on the diagonal, and the number of family connections between each pair of communities below the diagonal. The size of the circles is proportional to the number of connections. Orange and blue bar graphs in the lower part of the diagram show the number of connections across communities but within the intervention arm and control arm, respectively. The grey bar graph shows the proportion of connections across communities in different study arms. The diagram shows that each community was connected to almost every other community through family ties.Two‐thirds (64.7%, 3647/5637) of participants in the intervention arm agreed to take an HIV rapid test, whereas half (50.7%, 5087/10,028) of participants in the control arm agreed, leading to an overall risk difference of 13.6 (95% CI: 12.0−15.3). Of the 8734 participants who consented for an HIV test, HIV test results were recorded for 8700.
