Baseline demographic, clinical and immunological characteristics of RA patients included in the study.

Values are mean ± sd unless otherwise indicated. *values are reported as mean ± sd (median).RA = rheumatoid arthritis; TNF = tumor necrosis factor; DMARDs = disease modified anti-rheumatic drugs; CRP = C-reactive protein; ESR = erythrocyte sedimentation rate; DAS = disease activity score; HAQ = Health Assessment Questionnaire; CCP = cyclic citrullinated protein; RF = rheumatoid factor; MCV = modified citrullinated vimentin.除非另有说明，所有数值均以平均值±标准差（standard deviation, sd）表示。带*号的数值以平均值±标准差（中位数）形式报告。RA = 类风湿关节炎（rheumatoid arthritis）；TNF = 肿瘤坏死因子（tumor necrosis factor）；DMARDs = 改善病情抗风湿药（disease modified anti-rheumatic drugs）；CRP = C反应蛋白（C-reactive protein）；ESR = 红细胞沉降率（erythrocyte sedimentation rate）；DAS = 疾病活动度评分（disease activity score）；HAQ = 健康评估问卷（Health Assessment Questionnaire）；CCP = 环状瓜氨酸肽（cyclic citrullinated protein）；RF = 类风湿因子（rheumatoid factor）；MCV = 修饰型瓜氨酸波形蛋白（modified citrullinated vimentin）。
