Table 3.
Stair negotiation time in groups of no change, decline, and improvement in 2 anchors and the estimates of anchor-based meaningful changes.
| Functional change in ADL |
No change in disability score (n = 197) |
Increased in disability score (worsening) by ≥1 points at f/ua (n = 113) |
Meaningful decline estimate |
Decrease in disability score (improvement) by ≥1 points at f/ua (n=61) |
Meaningful improvement estimate |
