Numbers of patients with characteristic/total number of patients (%).
CRP = C-reactive protein, ESR = erythrocyte sedimentation rate, AST = aspartate transaminase, ALT = alanine transaminase, ALP = alkaline phosphatase, RF = rheumatoid factor, anti-CCP = anti-citrullinated protein antibody, ANA = antinuclear antibody, HLA = human leukocyte antigen.
