Figure 1: ROC curve of placental growth factor in serum of patients and control groups. Area under the curve=0.872 (<0.001), 95% CI (0.781–0.962) at a cutoff point of 151, sensitivity=75.0%, specificity=72.1%, positive predictive value=44.1%, negative predictive value=90.7%, accuracy of the test=72.7%.
