Baseline characteristics of study subjects according to serum uric acid quintiles.

Data are presented as mean (SD) or median (IQR). The subjects were grouped according to quintiles of serum uric acid: quintile 1 (≤295 µmol/L), quintile 2 (296–332 µmol/L), quintile 3 (333–367 µmol/L), quintile 4 (368–409 µmol/L), and quintile 5 (≥410 µmol/L), for male; and quintile 1 (≤205 µmol/L), quintile 2 (206–232 µmol/L), quintile 3 (233–262 µmol/L), quintile 4 (263–298 µmol/L), and quintile 5 (≥299 µmol/L), for female. HDL, high-density lipoprotein; LDL, low-density lipoprotein.
aP values are based on χ2 test for categorical data and on Kruskal-Wallis H test or one-way analysis of variance for continuous data, depending on the normality of the data.
