Meanwhile, Kaplan–Meier survival analysis demonstrated that 9 genes (i.e. ITGB6, CD36, ITGA3, LAMC2, ITGA2, LAMA3, ITGB4, COL11A1, and LAMB3) of 13 differentially expressed ECMGs were discovered to be remarkably linked to PAAD prognosis (Figures 3C–O). Here, ITGB4 is linked to pancreatic adenocarcinoma.
