aAdjusted for age, height, ever smoked, diabetes, rheumatoid arthritis, heart disease, and asthma. bFurther adjusted for leptin or cfurther adjusted for interleukin-6. Dependent variable, JSN grade (0-2) in superior or axial compartment. Independent variable, BMI, WHR, trunk fat, or total fat (all except BMI expressed as percentages between 0 and 100%). IL-6, interleukin-6; CI, confidence interval; JSN, joint-space narrowing; BMI, body mass index; WHR, waist-to-hip ratio.
