Regression model estimates illustrating the association of disease activity with EQ-5D score differences (∆EQ-5D) between the general population and patients with RA (n = 2912). Estimates were adjusted for age, marital status, education level, body mass index, exercise, smoking status, disease duration, extraarticular features, joint surgery, IgM-rheumatoid factor status, comorbidities, and treatment with methotrexate, biological antirheumatic drugs and glucocorticoid.
