Comparison of Perceived change between groups with Low versus High baseline scores, while controlling for Measured change scores

Baseline scores	Measured Change	Perceived Change (unadjusted)	Perceived Change (adjusted)	P-value*
Ability to walk leisurely
Low: Self-paced 5-m gait speed < 0.8 m/s, n=9	0.07 ± 0.11 (−0.05, 0.32)	+1.7 ± 2.3 (−2, +5)	1.62 ± 0.71	0.60
High: Self-paced 5-m gait speed ≥ 0.8 m/s, n=13	0.06 ± 0.15 (−0.22, 0.27)	+2.1 ± 2.2 (0, +6)	2.11 ± 0.59
Ability to walk fast
Low: Fast-paced 5-m gait speed < 1.38 m/s, n=14	0.03 ± 0.11 (−0.18, 0.28)	+1.1 ± 1.8 (−2, +5)	1.37 ± 0.55	0.81
High: Fast-paced 5-m gait speed ≥ 1.38 m/s, n=8	0.13 ± 0.15 (−0.09, 0.41)	+2.1 ± 2.8 (0, +7)	1.61 ± 0.75
Ability to walk long period of time
Low: 6MWT distance < 288m, n=12	20.6 ± 42.3 (−27, 105)	+0.4 ± 1.7 (−2, +5)	0.47 ± 0.45	0.006**
High: 6MWT distance ≥ 288m, n=10	25.8 ± 41.7 (−53, 82)	+2.6 ± 1.8 (0, +5)	2.54 ± 0.49

Values are mean ± SD (min, max) for unadjusted means, mean ± SE for adjusted means. Abbreviation: 6MWT – 6-Minute Walk Test
