Adjusted probabilities (95% confidence intervals) of transitioning between preand post-Q-SNF trajectories

	Post-Q-SNF trajectory
Pre-Q-SNF trajectory	Substantial improvement	Little improvement	No improvement
Minimal disability	0.52 (0.46–0.70) (n=83)	0.32 (0.19–0.39) (n=38)	0.16 (0.03–0.23) (n=20)
Mild disability	0.05 (0.03–0.22) (n=16)	0.56 (0.39–0.70) (n=89)	0.38 (0.19–0.53) (n=66)
Moderate disability	0.00	0.15 (0.00–0.47) (n=12)	0.85 (0.53–1.00) (n=57)

The model was adjusted age, sex, race, educational level less than high school, number of chronic conditions, physical frailty, cognitive impairment, depressive symptoms, and type of hospital admission (acute or elective), based on information available immediately before or during the hospital admission. The probabilities were calculated with Bayes’ rule, and the corresponding 95% Confidence Intervals (CI) were estimated with bootstrapping using 1000- samples. Figure 1 and Table 2 are interconnected. Participants in the substantial improvement group in the post-Q-SNF trajectory (figure 1, panel B) come from those with minimal disability (n=83) and mild disability (n=16) in the pre-Q-SNF trajectory (figure 1, panel A).
