| Low (n=17) | Moderate (n=23) | High (n=37) | p Value | |
| Median | Median | Median | ||
| Injury burden* | 149.6 | 108.1 | 112.6 | 0.169 |
| Incidence of severe injuries† | 1.2 | 1.0 | 0.8 | 0.111 |

*Number of severe injuries (causing more than 28 days of absence from training and matches) per 1000 hours of exposure ((Σ severe injuries/Σ hours of exposure) × 1000).
†Number of days of absence per 1000 hours of exposure (Σ days of absence/Σ hours of exposure × 1000).
