Figure 7

Receiver operating characteristic (ROC) curves analysis of potential biomarkers (group W vs M; group HD vs M). The area under the ROC curve was called Area Under Curve (AUC), which was used to assess the sensitivity and specificity of biomarkers for predicting events. We regarded AUC > 0.85 as the bottom line of very high prediction accuracy.
