  1. aThe demographic data included the age, body height and weight; the results showed that the age and the body weight were not the risk factors of ACL injuries, the body height was the risk factor of ACL injuries for males, but not for females
  2. bThe notch volume here was the mean value of the eight times multivariate logistic regression analysis
