immune microenvironment of DRLs prognostic model. (A). The box plot exhibiting the expression level of immune checkpoint genes between the high- and low-risk groups. (B). The single-sample gene set enrichment analysis (ssGSEA) displaying the extent of immune cell infiltrations in the high- and low-risk groups. (C). The ssGSEA analysis indicating the functions of immune cell subpopulations between the high- and low-risk groups. (D-F). The ESTIMATE score, immune score, and stromal score in the high- and low-risk groups. *p < 0.05, **p < 0.01, ***p < 0.001
