  1. Data are expressed as mean ± SD or number (%). Data are presented for 1137 patients, but when data are missing, the numbers of patients are given. RF = rheumatoid factor, ACPA = anti-citrullinated protein antibody, DAS28 = disease activity score of 28 joints, HAQ = health assessment questionnaire, bDMARDs = biological disease-modifying anti-rheumatic drugs, csDMARDs = conventional synthetic disease-modifying anti-rheumatic drugs
