| Kinetic parameters | ABT-116 (n = 12) | Carprofen (n = 11) | Tramadol (n = 9) | Placebo (n = 9) |
| Peak Vertical Force | 4.4 ± 6.8 | 1.2 ± 7.5 | 2.1 ± 4.9 | 2.8 ± 10.6 |
| Statistical Power | 0.07 | 0.07 | 0.05 | |
| Sample Size for Power > 0.8 | 485 | 445 | >1000 | |
| Peak Vertical Impulse | 2.3 ± 13.4 | 2.4 ± 7.1 | −1.1 ± 6.9 | −1.8 ± 6.9 |
| Statistical Power | 0.14 | 0.24 | 0.05 | |
| Sample Size for Power > 0.8 | 100 | 45 | >1000 | |
| Falling Slope | −3.2 ± 19.0 | −0.6 ± 16.2 | 4.6 ± 19.5a | 11.1 ± 35.2a |
| Statistical Power | 0.10 | 0.14 | 0.08 | |
| Sample Size for Power > 0.8 | 185 | 95 | 275 | |
Note: Data represent percentage change in Week 3 of the trial, when compared with mean baseline. Power analysis results compare each treatment group with placebo. aFalling slope is more negative after treatment (undesirable effect).
