Mortality rates decreased with increasing gestational age. More than 90% of neonates born at 28\u201333\u2009weeks had morbidity, with the rate of morbidity decreasing from 34\u2009weeks. The odds of mortality were no different following labour induction (aOR 1.22, 95% CI, 0.72\u20132.09) or prelabour caesarean (aOR 1.04, 95% CI, 0.63\u20131.73) compared with spontaneous labour. The odds of morbidity were higher among pregnancies following labour induction (aOR 1.53, 95% CI, 1.31\u20131.80) and prelabour caesarean section (aOR 2.14, 95% CI, 1.84\u20132.50) than spontaneous labour.
