Lenehan (2010)		n = 17	n = 56	Group differencea:
Prospective observational study	FIM total score improvement from discharge to 12-months	NR	NR	6.92 (95% CI = −0.11 to 13.96), P = .0537
	FIM motor sub-score improvement from discharge to 12-months	NR	NR	7.79 (95% CI = 0.09 to 15.49), P = .0474

Abbreviations: CI, confidence interval; FIM, Functional Independence Measure; NR, not reported.

^aAuthors reported that regression with propensity scoring was done to adjust for potential selection bias; however, details were not provided.
