A Cox regression analysis of IRPR score across 33 cancer types, where p-values are adjusted with Benjamini and Hochberg method for multiple testing. Red color indicates positive association (HR>1) and blue color negative association (HR < 1). B Radar chart of the Spearman correlation between IPRP score and expression of CD47, CTLA4, CD274, and TMB level. The outer side represents a positive correlation, and the inner side represents a negative correlation. The colors mark the immunotherapy targets and the asterisks indicate the statistical significance (p < 0.05, Spearman correlation). C Tumor microenvironment (TME) and immune infiltration (ssGSEA) analysis, where x indicates no significant association (p > 0.05). Statistical significance was assessed with Wald’s test for Hazard ratio for patient prognosis, Spearman correlation for immune-related scoring, and permutation test for ROC-AUC values.
