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

  • * Denominator has been adjusted to exclude missing data.

  • Denominator has been adjusted to exclude stillbirths, which would not be expected to have data at 3 days.

  • Denominator has been adjusted to exclude stillbirths and neonatal death < 7 days, which would not be expected to have data at 10 days.
