Figure 2. Inter-group immune feature analysis in TCGA. (A) Immune cell correlations in cluster 1. Colors and square sizes in the graph represent the correlations. The larger the square area, the larger the absolute correlation value; (B) Immune cell correlations in cluster 2; (C) Combined plot of PD-1 gene expression. The symbols above indicate significance levels, with ^**** denoting P < 0.0001; (D) Combined plot of PD-L1 gene expression. The symbols above indicate significance levels, with ^**** denoting P < 0.0001. TCGA: The Cancer Genome Atlas.
