Values are presented as mean±standard error or percentage.

BMI: body mass index, hs-CRP: high sensitivity C-reactive protein, eGFR: estimated glomerular filtration ratio.

Quartiles of serum uric acid (mg/dL): Q1, the 1st quartile (5.0 in males and 3.7 in females); Q2, the 2nd quartile (5.1−5.8 in males and 3.8−4.3 in females); Q3, the 3rd quartile (5.9−6.7 in males and 4.4−4.9 in females); Q4, the 4th quartile (6.8 in males and 5.0 in females).

Analysis of variance was used for continuous variables and the chi-square analysis was used for categorical variables.
