  Warfarin 2.06 1.01 – 4.2 0.048
Clinical, e’ velocity, and 2-D Echo Model-8*
  e’ velocity (per  1 cm/sec) 0.85 0.7 – 0.97 0.01
  LVEF (per 10 point) 1.0 0.8 – 1.2 0.98
  LAVI (per 10 mL/m2) 1.61 1.2 – 2.2 0.002

  1. CI: confidence intervals; LVEF: left ventricular ejection fraction (%); LAVI: left atrial volume index (mL/m2). * The Hosmer and Lemeshow test of the final models (7 and 8) showed good fit (P values = 0.25 and 0.75, respectively).
