Note: The dependent variable in all columns is an indicator equal to one if the child was born in a health facility. Exposed is an indicator equal to 1 if the birth occured during the intervention period and 0 if it occurred before. The sample consists of births in the ten years preceding the intervention (since 2006) and excludes Gombe state. In each column the dependent variable is regressed on the exposure indicator and time trends. All models include mother fixed effects. Separate models are estimated for participants in the treatment and control groups. Standard errors in parentheses are clustered at the level of the health service area (HSA).
