Results of univariable proportional hazards models predicting all-cause mortality: hazard ratios, 95% confidence intervals, and P values for selected clinical and echocardiographic variables

	HR (95% CI)	P value
Age (10 yr)	1.17 (0.97–1.42)	0.098
NT-pro BNP (2000 pg/ml)	2.02 (1.65–2.48)	<0.001
LV ejection fraction (10%)	0.63 (0.50–0.79)	<0.001
LV end-diastolic volume index (25 ml/m²)	1.40 (1.23–1.60)	<0.001
Deceleration time (100 ms)	0.65 (0.45–0.95)	0.020
MR area (5 cm²)	1.42 (1.17–1.73)	<0.001
LA volume index (20 ml/m²)	1.66 (1.41–1.95)	<0.001
Tricuspid annular excursion (0.5 cm)	0.70 (0.57–0.87)	0.001
TR area (5 cm²)	2.00 (1.49–2.75)	<0.001
RA volume index (20 ml/m²)	1.78 (1.41–2.24)	<0.001

Hazard ratio and confidence interval calculations were based on changes of approximately 1 SD (indicated in parentheses) for continuous variables.

CI = confidence interval; HR = hazard ratio; LA = left atrial; LV = left ventricular; MR = mitral regurgitation; RA = right atrial; TR = tricuspid regurgitation.
