Kaplan-Meier plot showing achievement of sustained DMARD-free remission by category of MBDA score for all RA patients (a), ACPA-positive RA patients (b) and ACPA-negative (c) RA patients. Vertical lines indicate that a patient is censored. The numbers below the figures denote the number of patients at risk in each group. Visual representation of the data was restricted to 5 years follow-up since thereafter the number of patients was small. DMARD, disease-modifying antirheumatic drug; RA, rheumatoid arthritis; ACPA, anti-citrullinated protein antibodies; MBDA, multi-biomarker disease activity
