  1. Early MDA MDA within 3 months, Late MDA MDA between 3 and 12 months, Never MDA no MDA within first year, SF36 Short Form-36, PCS Physical Component Scale, MCS Mental Component Scale. All analyses corrected for baseline score, gender, age, symptom duration, use of disease-modifying antirheumatic drugs, erosive disease at baseline, and baseline disease activity (SJC, TJC, LEI, PASI, VAS global, VAS pain and HAQ)
