Tumor microenvironment (TME) and immune landscape differences between clusters. (A) Tumor purity differs significantly between C1 and C2. (B–D) ESTIMATE analysis shows higher immune and stromal scores in one cluster. (E) Immune cell infiltration analysis reveals distinct TME profiles between clusters. (F) Immune-related gene expression varies, particularly in checkpoint molecules and regulators. * Symbols denotes, A single * denotes a p-value of less than 0.05, indicating a statistically significant difference. Two ** represent a p-value of less than 0.01, suggesting a highly significant difference, while three *** indicate a p-value of less than 0.001, reflecting a very highly significant difference.
