Anti-Cyclic Citrullinated Peptide Antibodies and Severity of Interstitial Lung Disease in Women with Rheumatoid Arthritis

Figure 2

Anti-cyclic citrullinated peptide (anti-CCP2) titers in patients with rheumatoid arthritis without interstitial lung disease (RA-only), compared with patients with rheumatoid arthritis and interstitial lung disease (RA-ILD) group. The cut-off value of anti-CCP2 for positivity was 20 U/mL. Horizontal bars indicate the median. values for the comparison of anti-CCP2 titers between groups were obtained by Mann-Whitney test.
