		Odds-Ratio	95% CI	P value
Clinical	Model-6
	CHADS₂ Score ( per 1 point)	1.39	1.2 – 1.7	0.001
	Warfarin	2.22	1.4 – 3.7	0.002
Clinical, E/e’, and 2-D echo	Model-7*
	E:e’ (per 1 point)	1.07	1.002 - 1.1	0.04
	LVEF (per 10 point)	0.95	0.8 – 1.2	0.63
	LAVI (per 10 mL/m²)	1.53	1.13 – 2.1	0.006
	CHADS₂ ( per 1 point)	1.22	0.9 – 1.6	0.20
	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
	CHADS₂ ( per 1 point)	1.18	0.9 – 1.6	0.29
	Warfarin	1.94	0.94 – 4.0	0.07

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).
