Spearman Correlations of WISCI With Other Endpoints at 3, 6, and 12 Months and on Change From Baseline

N	Outcome Measure
N	LEMS (n = 107–121)	Speed (n = 80–88)	6MW-D (n = 76–78)	LFIM (n = 104–121)	Total FIM (n = 106–117)	BBS (n = 107–120)
At 3 months	0.85	0.78	0.76	0.92	0.73	0.91
At 6 months	0.85	0.85	0.68	0.89	0.77	0.89
At 12 months	0.88	0.77	0.69	0.88	0.74	0.92
Change baseline:
to 3 months	0.55	^*	^*	0.87	0.54	0.85
to 6 months	0.60	^*	^*	0.88	0.48	0.87
to 12 months	0.64	^*	^*	0.87	0.51	0.85

N is sample size. All correlations are statistically significantly different from 0 (P < .001). WISCI = Walking Index for Spinal Cord Injury; LEMS = Lower Extremity Motor Score; 6MW-D = 6-minute walk distance; FIM = Functional Independence Measure; LFIM = FIM locomotor score; BBS = Berg Balance Scale.

Insufficient data; only 14 participants had any ability to walk at baseline; none could complete 6MW.
