OP12.08: Role of progesterone, cerclage and pessary in preventing preterm birth in twin pregnancies: a systematic review and network meta-analysis To determine the role of progesterone, pessary and cervical cerclage in reducing the risk of preterm birth (PTB) in twin pregnancies. Twin pregnancies with short cervix (£25 mm): pessary (p = 0.8), vaginal progesterone (p = 0.2), IM 17-OHPC (p = 0.09) or cerclage (p = 0.16) did not reduce the risk of PTB < 34 weeks.
