†Adjusted ORs were calculated using a logistic regression analysis and were adjusted for maternal age, region, nulliparity, history of spontaneous abortion, history of diabetes and history of hypertension.
GDM, gestational diabetes; HELLP, haemolysis, elevated liver enzymes and low platelet count; NA, not applicable; PPH, postpartum haemorrhage; PPROM, preterm premature rupture of membranes; PIH, pregnancy-induced hypertension; SLE, systemic lupus erythematosus; TPROM, term premature rupture of membranes.
