Days at home out of the hospital by FI slope progression quartile.

	Mean (SD) DAH out of the hospital	Rate Ratio (95% CI)	P-Value
Quartile 1	308.6 (93.0)	Ref	Ref
Quartile 2	300.0 (99.3)	0.972 (0.970, 0.975)	<0.001
Quartile 3	290.4 (104.5)	0.941 (0.939, 0.943)	<0.001
Quartile 4	270.4 (112.3)	0.876 (0.874, 0.878)	<0.001

Shown is the mean (standard deviation; SD) number of days alive at home (DAH) out of the hospital by quartile of frailty progression, among frailty progressors (claims-based frailty index slope > 0.09). Numerically higher quartiles indicate faster frailty progression. Also shown is the rate ratio and 95% confidence interval (CI) for DAH for each quartile using quartile 1 as reference (Ref).
