  1. Model 1: no covariates were adjusted;
  2. Model 2: adjusted for age, gender, BMI, race, education level, RIP, smoking status, alcohol drinking status, metabolic equivalent;
  3. Model 3: adjusted for covariates in model 2 plus SBP, TC, eGFR, total 25-hydroxyvitamin D, serum calcium, serum phosphorus, and NLR.
  4. HbA1c: hemoglobin A1c; OR: odds ratio; CI: confidence interval; BMI, body mass index; RIP, ratio of family income to poverty; SBP, systolic blood pressure; TC, total cholesterol; eGFR, estimated glomerular filtration rate; NLR, neutrophil-lymphocyte ratio; AAC, abdominal aortic calcification
