Figure Lengend Snippet: RA-Specific Serum IgG Antibodies in DBA/1J Mice. Sera were collected biweekly from DBA/1J mice immunized with bovine type II collagen (bCII) (arthritic: N = 9–18; non-arthritic: N = 17–37), or PBS (N = 14) and tested via indirect ELISA for A) anti-CitP, and B) anti-HomoCitP IgG antibodies. Graphs show the median [IQR] for each group, with a cut-off indicating the limit of detection (dashed line). Statistical analysis was performed using a mixed effects model with the Geisser-Greenhouse correction and Tukey's multiple comparisons test. The resulting p-values are indicated on the graphs.
