Deemed planned CD for any of the following indications: desired repeat CD, placenta previa, malpresentation, history of shoulder dystocia, macrosomia, or other nonemergent condition(s) that precluded attempt of labor or vaginal delivery, unless such condition occurred after initiation of labor induction
A total of 23 patients (4 in the PRE group and 19 in the POST group) who were admitted in the late evening hours at 38+6 weeks gestation for elective 39-week induction of labor were included in the ≥39-week group for analysis.
