ALB and aneurysm: The results of the univariate Cox regression analysis showed that age(HR = 1.083, p< 0.001), renal impairment (HR = 5.57, p<0.001), platelets (PLT) (HR = 0.993, p< 0.015), NLR (HR = 1.128,p< 0.001), HRR (HR = 0.783, p< 0.001), albumin (HR =0.813, p< 0.001), and aneurysm diameter (HR = 1.045, p<0.001) were risk factors for death.
