Figure 7. The association between CLCN4 gene expression and 22 immune cells infiltration levels. (A) The correlation between CLCN4 expression and immune cell infiltration was calculated according to EPIC algorithm. (B) The correlation between CLCN4 expression and immune cell infiltration was calculated according to the TIMER algorithm. (C) The correlation between CLCN4 expression and immune cell infiltration was calculated according to XCELL algorithm. *p < 0.05, **p < 0.01, ***p < 0.001.
