As depicted in Figure 3B, the findings of univariate Cox regression analysis illustrated that 10 genes (i.e. COL5A2, ITGA3, LAMA3, ITGB6, FN1, ITGB4, ITGA2, LAMC2, COL11A1, and LAMB3) of 13 differentially expressed ECMGs were detected to be significantly associated with PAAD prognosis. Here, ITGB4 is linked to pancreatic adenocarcinoma.
