The data are shown as median (interquartile range) or number/total number (percentage).
CD, cesarean delivery; IOL, induction of labor; POST, post-implementation deliveries; PRE, pre-implementation deliveries; SROM, spontaneous rupture of membranes.
aDual agent indicates misoprostol plus Foley balloon placed within 1 hour of each other as initial induction method.
