Notes: All ORs were adjusted for age (continuous), drinking (yes/no), smoking (yes/no), living area (urban/rural), carbohydrate intake (continuous), fat intake (continuous), protein intake (continuous), BMI (continuous), eGFR (continuous), hypertension (yes/no), dyslipidemia (yes/no) except for each stratifying factor. ORs and 95% CI were presented for individuals with SUA levels in the highest quartile compared to those in the lowest quartile.

Abbreviations: OR, odds ratio; CI, confidence interval; SUA, serum uric acid; IFG, impaired fasting glucose.
