ROC curves showing the best diagnostic ability to predict patient response to TACE. A Individual ROC curves for the predictors total tumor diameter (blue), absence of CTC clusters at baseline (red), and CTC increase ≥ 15% at D1 (green). B ROC curve for the combination of total tumor diameter and CTC increase ≥ 15% at D1 by logistic regression. Data for AUROC (95% confidence interval) are shown
