*
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.
