Role of Blood Stasis Syndrome of Kampo Medicine in the Early Pathogenic Stage of Atherosclerosis: A Retrospective Cross-Sectional Study

Figure 2

The diagnostic accuracy of blood stasis (BS) syndrome + impaired glucose tolerance (IGT), BS syndrome alone, IGT alone, and dyslipidemia (DLP) for predicting flow-mediated dilation (FMD). The receiver operating characteristic (ROC) curves depict that BS syndrome and IGT have good diagnostic utility for FMD, with BS syndrome + IGT having better diagnostic accuracy; DLP demonstrates poor diagnostic utility. In each graph, the solid diagonal line is the line of no discrimination (true area = 0.50), and the optimal cutoff points are indicated on the curves. AUC: area under the curve; CI: confidence interval.
