The continuous variables were presented as either the mean ± standard deviation or the median with interquartile range, and p values were calculated using t-tests for normally distributed variables and Mann–Whitney U tests for non-normally distributed variables. Categorical variables were expressed as percentages and frequencies, and p values were computed using weighted chi-square tests. BMI, body mass index; SUA, serum uric acid; TC, total cholesterol; AST, aspartate aminotransferase; ALT, alanine aminotransferase; SII, systemic immune-inflammation index; CHD, coronary heart disease.
