Sample size estimation
| Outcome measure | Variance estimate | SEM | Initial sample size estimate |
| VO2peak (mL/kg/min) | 1.69 | 1.0 | 29 |
| Non-paretic limb knee extension strength (Nm) | 72.3 | 10.6 | 11 |
| Paretic limb knee extension strength (Nm) | 43.6 | 12.4 | 5 |
| Non-paretic limb knee flexion strength (Nm) | 17.6 | 7.4 | 5 |
| Paretic limb knee flexion strength (Nm) | 16.8 | 10.1 | 3 |
The non-inferiority limit is the SEM. The sample size is the number of participants required per group.
SEM, SE of measurement.
