* Adjusted for: age, severe co-morbid illness of the mother, lung diseases, ante-partum haemorrhage/abruption placentae/placenta praevia, eclampsia/pre-eclampsia, foetal-pelvic disproportion/excessive development of the infant, oligohydramnios, premature rupture of the membranes, abortion threats/assisted fecundation, congenital malformation, post-maturity and macrosomia.
† The % variation is computed as (crude RR-adj RR)*100/crude RR.
