Figure 6. Correlation analysis between FAP expression and macrophages infiltration. (A) Different algorithms showed the correlation between FAP expression and macrophage infiltration in human cancers. (B) Classic scatter plotters were presented in STAD, READ, PAAD, HNSC, COAD, and ESCA. The p-values and Rho values were obtained via the purity-adjusted Spearman’s rank correlation test.
