  1. ABSI: a body shape index, BRI: body round index, HR: hazard ratio, CI: confidence interval;
  2. Model 1: adjusted for age, sex, race, and residence; Model 2: adjusted for age, sex, race, residence, smoking, drinking, systolic blood pressure, and diastolic blood pressure. The anthropometric measures were converted to a z score using the equation (X-Xmean)/XS
