Figure 1.
ELISA-based analysis of antibody reactivity against two proteins of MAP in RA subject and HCs. The sera was tested against plate-coated PtpA (A) and PknG (B) proteins. Bars represent the median ± interquartile range. Thresholds for antibody positivity are indicated by dashed lines. P-values are indicated above the distributions. ROC analysis of both proteins (C and D).
