Relapse rates of rheumatoid arthritis (RA) dependent on anticitrullinated protein antibody (ACPA) and multibiomarker disease activity (MBDA) score. (A) Risk chart for cumulative disease relapse over 1 year dependent on ACPA status and MBDA score. (−) indicates no ACPA or a low MBDA score (<30). (+) indicates presence of ACPA or moderate-to-high MBDA score (≥30). Values indicate the incidence of relapse over 1 year for that patient group. (B) Kaplan–Meier curves indicate loss of remission over 12 months in patients with RA in relation to ACPA status and MBDA score: (blue) ACPA/MBDA double-negative, (green) ACPA+/MBDA−, (yellow) ACPA−/MBDA+ and (purple) ACPA/MBDA double positive. Y-axis indicates the percentage of patients with RA in sustained remission (100% at baseline). X-axis indicates time.
