  • All variables are presented for the univariate analysis, but only variables with a  P value<0.05  are presented for the multivariate analysis.

  • *Variables achieving P<0.20 in the univariate analysis were entered into the multivariate model.

  • †Only variables achieving P<0.05 in the multivariate model are presented.

  • BMI, body mass index; FPKPA, frontal plane knee projection angle.
