  1. Model 1: unadjusted
  2. Model 2: adjusted for age, gender, and baseline SUA
  3. Model 3: further adjusted for education, income, smoking status, alcohol use, physical activity, history of hypertension, diabetes and dyslipidemia, antihypertensive agents, hypoglycemic agents, lipid-lowering agents, body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, total cholesterol, estimated glomerular filtration rate, and high-sensitivity C-reactive protein
  4. Abbreviations: CI Confidence interval, HR Hazard ratio, SUA Serum uric acid
  5. aIncidence rate per 1000 person-years
  6. bSensitivity analysis was adjusted for average body mass index, systolic blood pressure, diastolic blood pressure, fasting blood glucose, estimated glomerular filtration rate, high-sensitivity C-reactive protein, and SUA during the exposure period and other variables at baseline in model 3
  7. cSensitivity analysis excluded incident myocardial infarction or death within the first 2 years of follow-up and adjusted for variables in model 3
  8. dSensitivity analysis was adjusted for metabolic syndrome instead of its components and other variables in model 3
  9. eSensitivity analysis was conducted using Fine-Gray competing risk model considering non-MI deaths as competing risk events and adjusted for variables in model 3
  10. fSensitivity analysis excluded participants with cardiovascular or cerebrovascular disease and adjusted for variables in model 3
