Specifically, we observed positive correlations between the riskScore and 12 types of tumor-infiltrating cells (TICs), such as Macrophage M1_QUANTISEQ, T cell NK_XCELL, and T cell CD8 + _QUANTISEQ, while four TICs, including T cell CD4 + _EPIC and Neutrophil_MCPCOUNTER, exhibited negative correlations (Supplementary Table 3). This evidence concerns the gene CD4 and neoplasm.
