  2. Model 1 are unadjusted. Model 2 are adjusted for the factors of age, sex, body mass index. Model 3 are adjusted for the factors of model 1 covariates and diabetes mellitus, cardiovascular disease, residual renal function, hemoglobin, serum albumin, serum potassium, serum natrium, serum phosphorus, serum calcium, serum parathyroid hormone, serum creatinine, and fasting plasma glucose
