PGF and hypertensive disorder: For women who presented before 34 weeks of gestation, the addition of the sFlt‐1/PLGF ratio to hypertension and proteinuria significantly improved the prediction for subsequent adverse outcomes (area under the receiver operating characteristic curve (AUC) 0.93 for hypertension, proteinuria, and sFlt‐1/PLGF ratio versus 0.84 for hypertension and proteinuria alone; P < 0.001).
