Validation ROC curves of candidate metabolite biomarkers. a ROC curve in the second-trimester group. b ROC curve in the third-trimester group. c Calibration plot of the second-trimester group. d Calibration plot of the third-trimester group. X-axis shows average predicted probability values for each decile, and y-axis shows corresponding observed probability in each decile. Error bars represent 95% confidence intervals of mean predicted probabilities
