N, number of events; IR, incidence rate; HR, hazard ratio; aHR, adjusted hazard ratio; CI, confidence interval; BMI, body mass index.
aMultivariate-adjusted model was adjusted for age, income status, Charlson comorbidity index score, alcohol consumption, physical activity, smoking status, BMI, blood pressure, and fasting serum glucose and cholesterol levels.
