Maternal patients in the Solomon group had a higher incidence of history of preterm labor *p = 0.046.
aStatistical analyses between maternal patients undergoing selective vs Solomon techniques. Mean age and BMI were tested using Mann–Whitney t test, medical histories, and TTTS staging distribution were tested using categorical analyses.
