All estimates are adjusted for clustering at the CHW level.
*Preintervention and postintervention service area coverage and DID percentage point changes are unadjusted for covariates.
†Estimates for a random effects panel regression, with a treatment indicator that takes value 0 for the control arm and value 1 for the intervention arm. Combined estimates control for health catchment area.
CHW, community health worker; DID, difference-in-differences; UHC, universal health coverage.
