Study design. This figure shows the design of the overall study content. We divided 451 full-term singleton breech presentation parturient into planned vaginal delivery group (n = 429) and planned cesarean delivery group (n = 22), compared the obstetrical characteristics and neonatal outcomes between the two groups. And set a cephalic group, compared indicators mentioned above between cephalic group and breech one. We analyzed the indications for caesarean section in 17 emergency caesarean sections in the group planning for vaginal delivery, and compared the neonatal outcomes between it and the planned cesarean. Maternal perineal injury, stages of labor, types of breech presentation and 18 dead fetuses were analyzed in the vaginal delivery group.
