Multivariate Results for 12-Month Mobility Success

Risk Factor	RD^* (95% CI)	P
CIRU	.17 (.09 to .25)	<.001
Amputation level^†
TT	.05 (.02 to .13)	.006
TF	−.09 (−.41 to .24)	.60
Major depressive disorder at 4mo (yes)	−.23 (−.12 to −.34)	<.001
Alcohol score (points)	−.05 (−.03 to −.07)	<.001
Social support score (points)	.003 (.001 to .006)	.003
Total visits	−.0004 (−.004 to .003)	.78
Hospital site	.18 (.08 to .25)	.001

RDs generated from a negative binomial regression model represent an increase (or decrease if negative) in the success rate relative to reference category (site and total rehabilitation visits were also included in the model but were not statistically significant).

^†

TM is the reference category.
