TMB was elevated in the high-risk category relative to the low-risk category (P < 0.01) in Fig. 5D. In addition to this, the risk score was linked to the abundance of tumor-infiltrating immune cells (TIICs), including activated dendritic cells, natural killer cells, activated CD8 T cells, and activated B cells (Fig. 5E). Here, CD8A is linked to neoplasm.
