Fig. 3From: Serum RANKL levels associate with anti- citrullinated protein antibodies in early untreated rheumatoid arthritis and are modulated following methotrexateSerum concentration of ACPA and ACPA specificities. Graphs show the results of ELISA measurements of the antibody concentrations for patients being positive at baseline or at 3 months for the corresponding antibody: ACPA n = 120 (a), anti-cit-enolase (amino acids 5–21) n = 71 (b), anti-citrullinated (cit)-vimentin (vim) (amino acids 60–75) n = 67 (c), anti-cit-fibrinogen (fib) (amino acids 563–583) antibodies n = 42 (d). Horizontal lines represent median values, * p <0.05. Dotted lines delineate ELISA cutoff values for each antibody.
