Independent predictors for all-cause mortality

Multivariable analysis*	Parameters	aHR (95% CI)	P value
All-cause death during follow-up (4.82±3.94 years)	Age ≥59 years (mean age)	1.76 (1.26 to 2.47)	0.001
	Congestive cardiac failure	1.78 (1.33 to 2.38)	<0.001
	Chronic pulmonary disease	2.21 (1.36 to 3.59)	<0.001
	Malignancy	3.49 (1.73 to 7.07)	<0.001

Plus-minus value represents mean±SD.

*Multivariable Cox regression method was used to identify independent predictors for all-cause mortality. Only significant independent predictors are shown in the above table (see online supplemental table 3 for complete multivariable analysis results).
