a Weighted for sampling distribution of the population
b RRs were adjusted for hospital level, maternal age, maternal education, maternal marital status, history of caesarean section, number of antenatal visits, neonatal sex, use of anaesthesia, mode of delivery, foetal presentation, birthweight categories, gestational age categories, days that the mother stayed at the hospital after delivery, maternal complications and year of delivery (2012, 2013, 2014, 2015, 2016)
