Figure 4. CA9, CXCL9, and GIMAP7 regulate the immune infiltration of tumour microenvironment in PAAD. (A–C) The overall survival rate of the patients with PAAD were computed with the GEPIA web tool. (D–F) The Timer web tool was used to determine the association between the expression levels of CA9 (D), CXCL9 (E) and GIMAP7 (F) with the infiltration level of immune cells in PAAD samples.
