Model 1 was adjusted for age, sex, and race

Model 2 adjusted for age, sex, and variables with P < 0.05 after controlling for age and sex in the weighted logistic regressions. These variables included race, SBP, DBP, BMI, waist circumference, physical activity, metabolic syndrome, Hb, and HbA1c

Model 3 adjusted for all variables, including age, sex, race, BMI, waist circumference, physical activity, smoking status, metabolic syndrome, SBP, DBP, HbA1c, LDL-C, HDL-C, CRP, Hb, and platelet count
