Latency time from FLA to PPROM was significantly longer in the Solomon group compared to the selective group *p = 0.017.
aStatistical analyses between maternal patients undergoing selective vs Solomon techniques. Gestational ages at time of respective events and comparison of time latencies from FLA to IUFD and PPROM were examined using Mann–Whitney t tests. Incidence of post laser TAPs, TTTS recurrence, IUFD, PPROM, chorioamnionitis, and placental abruption were analyzed by categorial analyses.
