Figure 6. Correlation analysis between hub genes and immune characteristics. (A) Correlation between hub genes and immune cells shown by CIBERSORT analysis. (B) Association between hub genes and immune cells depicted by ssGSEA analysis. The colour spectrum, ranging from red to purple, illustrates the transition from positive to negative associations, respectively. A high number of asterisks and darker-coloured modules depict stronger associations. *P < 0.05; **P < 0.01; ****P < 0.001.
