Difference in perceived facility and home equipment availability at baseline, 6 months, and 12 months

Time		Mean	SD	Mean Diff	T(df)	p-value
*Facility availability*¹
Baseline:	SIM^†	9.92	4.34	−0.48	−2.07 (248)	p≤0.05
	STRIDE^‡	9.75	4.24	−0.92	−4.20 (238)	p≤0.001
6 months:	SIM	10.4	4.27	−0.39	−2.04 (248)	p≤0.05
	STRIDE	10.6	4.19	0.17	0.82 (238)	p=0.41
12 months:	SIM	10.8	4.09
	STRIDE	10.5	4.25
*Home environment*²
Baseline:	SIM	5.50	2.71	−0.70	−6.44 (248)	p≤0.001
	STRIDE	5.46	2.61	−0.35	−2.94 (238)	p≤0.01
6 months:	SIM	6.20	2.88	−0.27	−2.80 (248)	p≤0.01
	STRIDE	5.79	2.58	−0.18	−1.86 (238)	p≤0.10
12 months:	SIM	6.47	2.77
	STRIDE	5.97	2.64

Facility availability scale ranged from 0–18

Home equipment availability scale ranged from 0–15
