Pearson product moment correlation matrix among the variables of interest.
| Ankle varus moment | Knee varus angle | COPy | |
|---|---|---|---|
| Peak knee flexion angle | r = 0.707, P = 0.003 | r = 0.753, P = 0.001 | r = 0.794, P = 0.000 |
| Ankle varus moment | – | r = 0.811, P = 0.000 | r = 0.734, P = 0.002 |
| Knee varus angle | r = 0.811, P = 0.000 | – | r = 0.809, P = 0.000 |
| COPy | r = 0.734, P = 0.000 | r = 0.809, P = 0.000 | – |
