  1. ITT—intent-to-treat analysis comparing satisfaction among individuals in the intervention arm to individuals in the control arm using complete case analysis. CACE—sensitivity analysis using two-stage least squares to adjust the effect of the intervention for treatment compliance. The intervention assignment is used as an instrument for receipt of the HBC intervention. ITT with MI—sensitivity analysis using intent-to-treat with missing data multiply imputed using respondents’ location, age, education, and interviewer. All confidence intervals and p-values are adjusted for clustering at the ward level. For each level, the point estimate compares the likelihood of giving that response or a more positive response. For example, for the “satisfied” row in “how satisfied are you with the CHW program,” the intervention led to a 16-percentage-point increase in reporting they were satisfied or very satisfied with the CHW program rather than neutral, dissatisfied, or very dissatisfied
