Figure 6. Infiltrating immune content related to the IRGPI. (A) The abundance of 22 immune cells in the meta-training cohort. (B) Immune cell abundance within each risk group in the meta-training cohort. The top five immune cells ranked by abundance are contrasted. (C) The abundance of 22 immune cells in the meta-validation cohort. (D) Immune cell abundance within each risk group in the meta-validation cohort. The top five immune cells ranked by abundance were contrasted. P-values were calculated with the Wilcoxon test (* P < 0.05, ** P < 0.01, *** P < 0.001).
