Objectives To assess effectiveness and safety of Foley catheter versus vaginal misoprostol for term induction of labor. Study DesignThis trial randomly allocated women with singleton term pregnancy to 30-mL Foley catheter or 25-g vaginal misoprostol tablets. Primary outcome was cesarean delivery rate. Secondary outcomes were maternal and neonatal morbidity and time to birth. Additionally, a systematic review was conducted. ResultsFifty-six women were allocated to Foley catheter, 64 to vaginal misoprostol tablets. Cesarean delivery rates did not differ significantly (25% Foley versus 17% misoprostol; relative risk [RR] 1.46, 95% confidence interval [CI] 0.72 to 2.94), with more cesarean deliveries due to failure to progress in the Foley group (14% versus 3%; RR 4.57, 95% CI 1.01 to 20.64). Maternal and neonatal outcomes were comparable. Time from induction to birth was longer in the Foley catheter group (36 hours versus 25 hours; p
