  • †Results are derived from three separate models (one per outcome) that were fitted using negative binomial regression with robust variance estimators and fixed effects at the commune level. The exposure variable is numeric and expressed by the cumulative frequency of terrorist attacks per commune. The same set of covariates was used in each model, two of which (the month and the percentage of missing observations) are not displayed here. The number of observations for cesareans is smaller because they are only performed in reference health facilities.
