The population was divided into DM and Non-DM groups for Cox analysis to examine the association between the BRI and new-onset CVD

Model 1: unadjusted; Model 2: adjusted for covariates including age, sex, and education level; Model 3: adjusted for covariates including age, sex, education level, BMI, CMI, HTN, dyslipidemia, smoking, drinking, physical activity, WBC, Plt, FBG, Cr, TC, TG, HDL-C, LDL-C, CRP, HbA1, HCT, and Hb
