Odds ratio and 95% confidence interval (CI) obtained from conditional logistic regression using the uninjured leg of ACL injured subjects and corresponding leg of control. Females and males analyzed as both separate and combined groups (Note MedVol and LatVol odds ratios correspond to the effect of a 100 mm3 increase and the odds ratios for the other variables correspond to a 1mm change).
