Clinical Evaluation of the Diagnostic Role of MicroRNA-155 in Breast Cancer

Figure 5

The Youden index three-group model for the role of miR-155 in the detection and differentiation of tumor grades, tumor stages, and tumor size in BC patients and comparison with healthy subjects: (a) relative expression level of miR-155 for low-grade (WD+MD) compared to high-grade (PD) and healthy groups, (b) relative expression levels of miR-155 for low-stage (I+II) compared to high-stage (III) and healthy groups, and (c) comparison of relative expression levels of miR-155 between ≤5 cm and > 5 cm tumor sizes and healthy group.
