Cox proportional hazards regression of factors related to all-cause mortality at 6 months in participants with available follow-up data (n=251)

	Frailty defined by Fried’s frailty phenotype		Frailty defined by REFS
	Adjusted HRs for mortality (95% CI)	P-value	Adjusted HRs for mortality (95% CI)	P-value
Frailty	2.65 (1.02–6.89)	0.04	4.19 (1.59–10.99)	0.004
Chronic pulmonary diseases	4.33 (1.55–12.09)	0.005	4.67 (1.66–13.17)	0.004
Admission due to falls	11.64 (1.40–96.76)	0.02	12.17 (1.46–101.21)	0.02
Cancer	18.92 (5.75–62.24)	<0.001	15.48 (4.61–51.87)	<0.001

Notes: Only the variables that had a P-value <0.20 in univariate regression were chosen for multivariate analysis. The final model contains only variables with P-value <0.05.
