Notes: Characteristics are reported as percentages for categorical variables and means (±SD) or medians (with interquartile range) for continuous variables. The study participants were divided into four groups based on the baseline levels of the quartile of Uric acid (⩽238.95, 239–284.60, 284.61–341.85, ⩾341.90 mmol/L). Categorical variables are presented as counts (percentages). The values outside the parentheses are the number of subjects, and the values inside the parentheses are prevalence. The quartile 1 level of Uric acid was used as the reference and quartiles 2, 3, 4 evaluated vs. quartile 1.
