Relationship between ACPA titer and disease activity. The relationship between ACPA titer and DAS28-ESR (a, n = 5967), CDAI (b, n = 6342), and SDAI (c, n = 6042) was plotted. CDAI, clinical disease activity index; DAS28-ESR, Disease Activity Score 28-joint count; SDAI, simplified disease activity index
