β: Partial regression coefficient
Model 1 = unadjusted linear regression model
Model 2 = adjusted for age and gender (Parameter estimates are for women; men = 0)
Model 3 = adjusted for age, gender, disability and pain
Model 4 = adjusted for age, gender, TNFα and IL-6
Model 5 = adjusted for age, gender, BMI and visceral adiposity
Model 6 = adjusted for age, gender, disability, pain, TNFα, IL-6, BMI and visceral adiposity
