M (SD) shown for age, BMI, height, weight, body fat percentage, RA duration, DAS-28 and HAQ score. DAS-28 was calculated using erythrocyte sedimentation rate, 28 swollen-and-tender joint count and visual analogue scale (overall health from 0 [very good] to 100 [very poor]). HAQ scores were defined as, ability to undertake activities of daily living (0, without any difficulty; 1, with some difficulty; 2, with much difficulty; 3, unable to do)
