  • All models include as covariates: the variables used in the matched randomization procedure (average monthly volume of deliveries at the nearest health centre and transfer time to comprehensive emergency obstetric and neonatal care hospital) and the cluster-average value of the outcome at baseline.

  • *Based on model with ln(total expenditure) as dependent variable.
