MTX use in Japanese patients with rheumatoid arthritis

We appreciate the letter from Dr. Carlos Antonio Moura and Dr. Carlos Geraldo Moura for their interest in our article [1]. As they noticed, that study was intended to evaluate the concordance of patient-reported joint symptoms, physician-examined arthritic signs, and ultrasound-detected synovitis in rheumatoid arthritis (RA), but not to evaluate the use of MTX. Although we described the median and range of RA duration (months) as 31 and 0-608, we should have clearly stated that 11 of 50 patients enrolled in that study were treatment-naive.This article is protected by copyright.
