Women with &lt;\u20093\u2009g\/24\u2009h had a median prolongation of 15.3\u2009days (interquartile range (IQR) 4.3 to 25.6), compared to 10.0\u2009days (IQR 5.0 to 19.6) with proteinuria between 3 to 5\u2009g\/24\u2009h; and 4.9\u2009days (IQR 3.8 to 11.7) for those with \u2265\u20095\u2009g\/24\u2009h. Increasing levels were also associated with increases in subsequent adverse composite maternal outcomes: 8.8% of women with &lt;\u20093\u2009g\/24\u2009h experienced maternal complications, compared to 16.1% with 3 to 5\u2009g\/24\u2009h, and 27.9% with \u2265\u20095\u2009g\/24\u2009h. There was no association with composite perinatal adverse outcomes. The sFlt\u20101\/PIGF ratio performed slightly better in predicting latency (area under the receiver operating characteristic curve (AUC) 0.78 vs. 0.67) but similarly in predicting adverse composite maternal outcomes (AUC 0.67 vs. 0.64).
