  • Gender and country of birth are represented as a frequency (%). The remaining variables are expressed as a mean±SD. The number of subjects (n) for each variable is in parentheses.

  • * Age, weight and body mass index (BMI) are self-reported values at the time of the first ACL rupture for the ACL group, as well as the NON sub-group, and at recruitment for the CON group. For the ACL group, age, weight and BMI at recruitment were 6.4±9.9 years (n=37), 0.7±4.5 kg (n=34) and 0.4±1.5 kg/m2 (n=33), greater than at the time of the first ACL rupture for the female participants, and 4.3±7.7 years (n=83), 1.6±4.7 kg (n=76) and 0.5±1.5 kg/m2 (n=73), greater than at the time of the first ACL rupture for the male participants.
