Quartiles based on serum uric acid levels: 1, <4.69 mg/dl; 2, 4.69–5.58 mg/dl; 3, 5.58–6.52 mg/dl; 4, ≥6.52 mg/dl
Model 3 was further adjusted for BMI, triglycerides, eGFR, blood urea nitrogen, serum creatinine, plasma total protein, globulin, alanine aminotransferase, and direct bilirubin
P < 0.05 was considered statistically significant
