Data are n (%), median (interquartile range), or mean ± standard deviation unless otherwise specified

Composite adverse outcome is composed of any one of the following occurrences: intrapartum fetal death, neonatal death, an Apgar score of 3 or less at 5 minutes, neonatal seizure, an umbilical artery blood pH of 7.05 or less with a base deficit of 12 mmol per liter or more, intubation for ventilation at delivery, or neonatal encephalopathy
