AMPA reactivity in early RA by the modified vimentin assay. Results from mod-Vim ELISA screening in 480 population controls and 1984 RA patients whereof 733 were ACPA negative by the CCP2 assay and 1249 were CCP2 positive. All antibody levels (Arg, Orn, Lys, Cit, Orn(Ac), Carb and Lys(Ac)) were significantly higher (p < 0.0001) in all RA patients, CCP2- RA, and CCP2+ RA, compared to the population controls using Kruskal-Wallis test with Dunn’s correction for multiple comparisons. The mod-Vim assay is based on the modified Vim58-69 peptide. Red lines depict medians.
