Figure 1. ROC curves and stacked histograms. ROC were used to calculate the Youden’s Index for the individual immunohistochemical markers to determine the optimal cut-off values. The stacked histograms show the expression of the markers among the two different groups. Curves and histograms for the markers PAX5 (A), CD15 (B), CD30 (C), PD-L1 on HRS cells (D), TARC (E), CD163 (F), CD68 (G), PD-1 (H), and PD-L1 in the TME(I).
