Univariate analysis (odds ratio (95%CI))p ValueMultivariate analysis (odds ratio (95%CI))*p ValueMultivariate analysis (odds ratio (95%CI))†p Value
*Odds ratio of cartilage defects per unit increase in the respective anthropometric and body composition measure after adjustment for age and gender in the regression equation.
†Odds ratio of cartilage defects per unit increase in the respective anthropometric and body composition measure after adjustment for fat-free mass and fat mass, ie, including age, gender, fat-free mass and fat mass in the regression equation.
‡Adjusted for age, gender and respective baseline variable in the regression equation.
