CI, confidence interval.
a Gender not recorded for 78 births.
b Includes the 78 infants without gender data.
c The rate of stillbirths was calculated from the number of women with known birth outcomes (n = 1280), while neonatal and perinatal mortality rates were derived from the number whose outcomes were known at 28 days (n = 1121) plus stillbirths, where appropriate.
d Rate-1 is stillbirths plus mortality within 7 days per 1000 births.
e Rate-2 is stillbirths plus mortality within 28 days per 1000 births.
