We further performed a multivariate stepwise regression analysis to evaluate the association between serum cystatin C levels and the Gensini score in a model including age, sex, BMI, smoking, hypertension, and diabetes as well as TC LDL-c, HDL-c, TG SBP, DBP, fibrinogen, FPG, eGFR and cystatin C. The adjustment for the covariates did not change the associations significantly. This evidence concerns the gene CST3 and diabetes mellitus.
