Outcome measures
Uterine rupture and uterine atony at or after vaginal misoprostol administration were defined as major complications in all groups. Total misoprostol administration time was calculated as the time from the first dose of misoprostol to the administration of the last dose. Total labor time refers to the time from the first dose of misoprostol to delivery. If a method other than vaginal misoprostol was used during the period until delivery, it was included in the ’total labor time’ period. Time intervals were defined as hours.
