√ Statistical significance based on p<0.05. (√) Borderline significant (0.08).
*The risk of prevalence when already being injured, taking into account the current duration (1st, 2nd, 3rd, etc weeks in a state of injury prevalence).
†The risk of prevalence when being in a state of risk (no prevalence the week before) or when being in a state of already injured (prevalence the week before).
