Fig. 2From: Rheumatoid factor isotypes in relation to antibodies against citrullinated peptides and carbamylated proteins before the onset of rheumatoid arthritisProportional Euler diagrams illustrating the relationships between, as an example, one anti-citrullinated protein antibody (ACPA), anti-CEP1 antibody (CEP1), immunoglobulin M rheumatoid factor (IgM-RF)/IgA-RF and anti-carbamylated protein antibodies (CarP). The numbers indicate the number of individuals positive for the antibody/RF of the pre-symptomatic individuals for each factor or combinationsBack to article page
