  1. LAVI left atrial volume index, LVMI left ventricular mass index, LVIDd left ventricular internal diameter at diastole, LVPWd left ventricular posterior wall thickness at end-diastole, RWT relative wall thickness, IVSd diastolic interventricular septum, DT deceleration time.
  2. *P < 0.05, **P < 0.01, and ***P < 0.001 for comparing the euthyroid group.
