HR and HR adjusted for age, sex, and FI-Lab21_admission for each 0.01 increment in score of ∆FI-Lab21 in relation to 6-month and 1-year mortality

∆FI-Lab21 and mortality	HR (95% CI)	P-value	Adjusted HR (95% CI)	P-value
Six-month mortality
∆FI-Lab21 (per each 0.01 increment in score)	0.980 (0.961–0.999)	0.040	0.941 (0.921–0.961)	<0.001
One-year mortality
∆FI-Lab21 (per each 0.01 increment in score)	0.987 (0.970–1.004)	0.126	0.947 (0.931–0.965)	<0.001

Note: ∆FI-Lab21= FI-Lab21_admission – FI-Lab21_discharge.

Abbreviations: Adjusted HR, hazard ratio adjusted for age, sex, and FI-Lab21_admission; FI-Lab21, 21-item frailty index based on laboratory blood and urine tests; ∆FI-Lab21, change of FI-Lab during hospital stay.
