ROC curves of cTB assay analyzed in a the training set, b after leave-one-out cross validation, and c independent test set for distinguishing PAS from non-PAS during all gestational age (GA, 6‒40 weeks). Area under the curves (AUC) with the sensitivity and specificity of the assays at the optimal cutoffs are listed for each graph. Comparison of ROC curves of cTB assay with or without ultrasound (US) for distinguishing PAS from non-PAS in d all GA (6‒40 weeks), e earlier GA (The first and second trimester, T1 + T2 < 24 weeks), and f late GA (T3 ≥ 24 weeks). AUC for each diagnostic model is listed for each ROC curve. Source data are provided in the Source data file.
