NOTE. Use of standard logistic regression: >1 odds ratio represents the increased likelihood of the outcome within the non-reference group, relative to the reference group. <1 odds ratio represents the decreased likelihood of the outcome within the nonreference group, relative to the reference group.

BMI, body mass index; IKDC, International Knee Documentation Committee; PT, physical therapy; ref, reference.
