And multivariate logistic regression analysis showed that disease duration, IL-6, and serum GRB2 levels were independent risk factors for T2DM combined with CAS (P<0.05), and serum GRB2 levels were a highly sensitive indicator of early AS (OR=1.405, 95% CI: 1.192-1.658 P<0.001) (Table 7). This evidence concerns the gene IL6 and type 2 diabetes mellitus.
