  1. Footnotes. Outcomes were adjusted by maternal age, maternal body mass index, gestational age at delivery, pregnancy at risk, parity, fetal presentation, number of fetuses, presence of previous CD, neonatal birth weight, grade of urgency (e.g. maternal or fetal compromise requiring immediate delivery) and cluster variables: centers with NICU and obstetric volume per center (number of deliveries/year).
  2. PPH, post-partum hemorrhage; TED, thromboembolic disease; BD, base deficit.
  3. *Any other condition requiring admission to Intensive Care Unit.
  4. **Any other condition requiring admission to Neonatal Intensive Care Unit in term neonates (37–42 weeks).
