↵* In multivariate analysis, we adjusted for age, body mass index, diabetes mellitus, hypertension, creatinine, albumin, hemoglobin, C-reactive protein, glucose, mean arterial pressure, high-density lipoprotein, low-density lipoprotein, triglycerides, smoking, alcohol consumption, and exercise.
↵** Sex showed a statistically significant interaction for the SUA level (p for interaction = 0.049). SUA: serum uric acid.
