aGeneralized linear mixed models adjusted for: maternal age (<20, 20-35, >35), maternal education (0, 1-4, 5-9, > = 10), parity, (0, 1-2, > = 3), antenatal visits (0, 1-3, > = 4), mode of delivery (vaginal or caesarean), hypertensive diseases (chronic or pregnancy-induced hypertension), malaria, other medical diseases (HIV, pregestational diabetes, cardiac/renal disease, chronic respiratory conditions, sickle cell anaemia), prelabour rupture of membranes, pre-eclampsia/eclampsia, vaginal bleeding in 2nd half of pregnancy and urine infection/pyelonephritis; facility and country as random effects.
