As shown in Table 2, univariate Cox regression analysis identified age, comorbid diabetes and CHD, use of lipid-regulating agents, higher levels of Hb, NLR, PLR, GLR, and SCr/CysC, along with lower levels of LMR and ALB, as risk factors for all-cause mortality (all p < 0.05). This evidence concerns the gene GSTM1 and diabetes mellitus.
