From: Prediction and prevention of hypertensive disorders of pregnancy
Scatter plot showing the relationship between the false-positive rate (FPR) and the sensitivity to predict early-onset preeclampsia (PE) by uterine artery Doppler (UAD) alone in the first trimester (a) and UAD alone in the second trimester (b). Closed circles indicate unselected or low-risk women, and closed triangles indicate high-risk women. When the FPR was <10%, the regression line of the sensitivity of FPR, including 0% FPR and 0% sensitivity, was plotted in unselected or low-risk women, and, when the FPR was ⩾10%, the regression line of the sensitivity on FPR, including 100% FPR and 100% sensitivity, was plotted in unselected or low-risk women.
