Objective Thresholds of minimal clinically important improvement (MCII) are needed to plan
and interpret clinical trials. We estimated MCIIs for the rheumatoid arthritis (RA) activity …

Objective. To develop a set of disease activity measures for use in rheumatoid arthritis (RA)
clinical trials, as well as to recommend specific methods for assessing each outcome …

Objective Simplified measures to quantify rheumatoid arthritis (RA) disease activity are
increasingly used. The minimum clinically important differences (MCID) for some measures …

Rheumatoid arthritis (RA) clinical trials often include at least 10 measures of disease activity
(eg, tender and swollen joint counts, erythrocyte sedimentation rate, patient pain, grip …

There is a growing interest in the use of patientreported outcomes in rheumatoid arthritis
(RA) clinical trials as well as in clinical practice (1). More and more, patients actively …

Introduction Frequent assessments of rheumatoid arthritis (RA) disease activity allow timely
adaptation of therapy, which is essential in preventing disease progression. However …

Objectives Disease Activity Score in 28 joints calculated with C-reactive protein (DAS28-
CRP) is used instead of erythrocyte sedimentation rate (DAS28-ESR) to assess rheumatoid …

Abstract Introduction The Rheumatoid Arthritis Impact of Disease (RAID) is a patient-
reported outcome measure evaluating the impact of rheumatoid arthritis (RA) on patient …

Over the years, the growing need to standardize methodologies in rheumatoid arthritis, to
improve the clinical management and evaluation of the effectiveness of treatments, has led …

Objective To compare the value of reporting treatment effects in rheumatoid arthritis (RA) as
