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
