  • Note: CI = confidence interval, PPV = positive pressure ventilation, RR = relative risk.

  • * Three infants were excluded from these outcomes owing to lethal malformations (1 in the multiparous planned home birth group, 2 in the multiparous planned hospital birth group).

  • Denominator was adjusted to exclude stillbirths and missing data.
