Model 3: model 2 further adjusted for other confounders
 Quartile 1 0.000
 Quartile 2 2.141 1.534–2.987 0.000
 Quartile 3 3.213 2.288–4.511 0.000

  1. 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
  2. Model 3 was further adjusted for BMI, triglycerides, eGFR, blood urea nitrogen, serum creatinine, plasma total protein, globulin, alanine aminotransferase, and direct bilirubin
  3. P < 0.05 was considered statistically significant
