Kaplan Meier survival curves of latency duration by first line tocolytic, in units with a liberal policy of tocolysis after PPROM. BM: betamimetic, CCB: calcium channel blocker, OA: oxytocin antagonist. There was no difference in Kaplan-Meier curves of latency duration by first line tocolytic (logrank test p = 0.43) in units with a liberal policy of tocolysis after PPROM.
