Among the clinical variables, IL6 had positive correlations with age (r=0.221, P=0.018), duration of diabetes (r=0.212, P=0.024), Cys C (r=0.299, P=0.002), and AST/ALT (r=0.314, P<0.001) and significant negative correlations with eGFR (r=−0.337, P<0.001) and 25(OH)D (r=−0.22, P=0.023). This evidence concerns the gene IL6 and diabetes mellitus.
