Change in 6-Minute Walking Distance from Baseline to 20 Weeks, Using Models for Adjustment

	Between Group Difference (95% CI)	P Value
Unadjusted for baseline 6-min walking distance (m)	−3.2 (−28.9 to 22.5)	.81
Adjusted for baseline 6-min walking distance (m)	−4.7 (−29.9 to 20.5)	.71
Adjusted for baseline 6-min walking distance (m) and age (y)	−3.7 (−28.6 to 21.2)	.77
Multiple imputation adjusted for baseline 6-min walking distance (m)	−5.0 (−28.5 to 18.5)	.67
Multiple imputation adjusted for baseline 6-min walking distance (m) and age (y)	−6.1 (−29.7 to 17.6)	.62
