Baseline and follow-up outcome measures by group, intention-to-treat analysis. Data are presented as medians (IQR).
| Characteristics | Intervention group (n = 40) | Control group (n = 39) | Between group differences | ||||
|---|---|---|---|---|---|---|---|
| Baseline | Three-month follow-up | Baseline | Three -month follow-up | Median estimate (95% CI) | Effect size | P-value | |
| Six-minute Walk Test, m | 476 (138) | 548 (142) | 497 (146) | 520 (173) | 30 (55 to 1) | 0.64 | 0.037 |
| Chair-stand Test, seconds | 11.6 (2.2) | 9.6 (1.9) | 11.4 (2.8) | 10.5 (2.4) | −0.88 (–0.02 to −1.72) | 0.64 | 0.034 |
| 10-metre Walk Test, m/s | 1.22 (0.33) | 1.31 (0.36) | 1.27 (0.38) | 1.31 (0.41) | 0.01 (−0.05 to 0.07) | 0.56 | |
| Short Physical Performance Battery, score (0–12) | 11 (1) | 12 (0) | 11 (2) | 12 (1) | 0 (0 to 0) | 0.86 | |
CI indicates confidence interval. Significance of Between Group Differences was analysed bythe Mann-Whitney U test. The median estimate was calculated using the Hodges-Lehmann test. The significance level was set at P < 0.05.
