Figure 1. Autoantibody profiles.

Figure 1

362 patients with rheumatoid arthritis had autoantibodies to post-translationally modified peptides measured. (A) The autoantibody profiles. Six main groups emerged in which the numbers within each group represented more than 5% of the total sample. Relevant segments of the Venn diagram are coloured. (B) Summarised autoantibody profiles. Venn segments are coloured when more than 5% of the population lies within a segment and this results in four groupings: single-positivity (green segment); double-positivity (yellow segment); triple-positivity (red segment); and negative for anti-modified peptide autoantibodies (outside the circles).
