N in each box of the second row corresponds to number of deliveries in the groups “before” and “after” the AIP training implementation. Difference in difference (DID) estimator was estimated using linear regression model. DID is presented as estimator (%) with 95% CI, and OR with 95%CI. The P-value is presented for DID estimator. CI: confidence interval; OR: odds ratio
