Distribution of ELISA signals of α-hnRNP-DLmir autoantibodies. Reactivities were predominantly found in SLE and RA. Prevalence of citrullinated α-hnRNP-DLmir (cit-DL) (A), α-hnRNP-DLmir (DL) (B) and the difference between cit-DL and DL signal (ΔDL) (C) in sera from Risk-RA patients (n = 71), early RA patients (LURA n = 106; EIRA n = 404), established RA patients (predict n = 127), SLE patients (n = 89), other diseases (n = 127) and healthy controls (n = 86) determined by ELISA. The dotted lines mark the cutoff versus other diseases (except SLE) or healthy controls with 98% specificity each. OD, optical density; SLE, systemic lupus erythematosus
