Health assessment questionnaire-disability index (HAQ-DI) score at the start of biological disease-modifying antirheumatic drug (bDMARD) therapy is associated with radiographic progression of large joint damage in patients with rheumatoid arthritis

Abstract

HAQ-DI score at the start of bDMARD treatment was associated with RPD to large joints during a therapeutic period of 1-3 years. Progressive damage is expected to increase when functional disability exceeds an HAQ-DI score of 1.5.
