Serum Mg levels were categorized by quartiles. Quartile 4 (higher serum Mg levels) was the reference group. Quartiles 2 and 3 showed no statistical significance. Adjustment for: Model 1: anthropometric factors (age, sex, waist circumference and SBP) and medication (insulin and diuretic use); Model 2: Factors related to glucose metabolism (glucose, HbA1c, HOMA-Beta and diabetes); Model 3: Factors related to lipid profile (HDL-C and ApoA-I); Model 4: Factors related to mineral metabolism and renal function (eGFR and serum creatinine). Model 1 + 2: Model 1 plus factors related to glucose metabolism. Model 1 + 3: Model 1 plus factors related to lipid profile. Model 1 + 4: Model 1 plus factors related to mineral metabolism. HDL-C, high-density lipoprotein-cholesterol; ApoA-I, apoliprotein A-I; HbA1c, hemoglobin A1c; HOMA-Beta, Homeostasis Model Assessment-beta cell function; eGFR, estimated glomerular filtration rate.
