Multivariate linear regression analyses and stepwise regression analysis were utilized to establish a prognostic gene model according to 13 PRGs (AIM2, CASP1, CASP5, CASP6, CASP8, CASP9, ELANE, GPX4, GSDMD, NLRP7, NOD2, PJVK, and PRKACA), which might predict the overall survival of CRC patients. The gene discussed is ELANE; the disease is colorectal carcinoma.
