Univariable and multivariable analyses of SPPB score and 6MWD for predicting a composite of all-cause death and heart failure readmission

	Unadjusted			Adjusteda
	HR	95% CI	P-value	HR	95% CI	P-value
SPPB score <7
	1.46	1.19–1.79	<0.001	1.28	1.01–1.61	0.049
6MWD <median

6MWD, 6-minutes walking distance; CI, confidence interval; HR, hazard ratio; SPPB, Short Physical Performance Battery.
