Coefficients with 95% CIs and P-values were estimated with generalized linear models. These coefficients correspond to the mean difference in birth rates for every additional unit increase in the independent variables. All variables are continuous, except for the overoccupancy of intensive care units (ICUs) (binary variable). Variables with a P < 0.10 in the univariable analysis were included in the multivariable analysis.
