Correlations between 8 key genes and infiltrating immune cells. Representative graphs showing the correlations of infiltrated immune cells with ALDH2 (A), ALDH9A1 (B), AUH (C), BNIP3 (D), ECHDC2 (E), LDHB (F), PDK4 (G), and SLC25A36 (H) expression. The correlation strength is shown as the dot size; the P values are expressed as the changes in the dot colour. P < 0.05 indicates a significant difference.
