  1. M1 = model 1, crude. M2 = model 2, adjusted for sociodemographic vulnerability and parity. M3 = model 3, adjusted for sociodemographic vulnerability, parity, mode of delivery, and gestational age. All covariates were binary, except gestational age which was continuous
  2. Risk scores represent each woman’s integer score on the Antepartum Risk Score tool (comprised of 46 weighted risk factors), and corresponds to the severity of prenatal medical risk
  3. Hosmer and Lemeshow tests performed on all M3 logistic regression models were P > 0.05, indicating satisfactory model fit
