The odds ratio represents the change in odds for a 100 g increase in birthweight.
The odds ratio represents the change in odds for a 0.01 increase in cord pH.
Mode of delivery was defined as emergency (assisted vaginal delivery and emergency caesarean section) and non-emergency (unassisted vaginal delivery and elective caesarean section).
