Figure 5From: IgG subclass antibodies to human and bacterial HSP60 are not associated with disease activity and progression over time in axial spondyloarthritisAntibody levels to Chlamydia pneumoniae, C. trachomatis and C. trachomatis HSP60 in the SpA cohort and the control group. Serum levels (µg/ml) of IgG1 and IgG3 against (A) C. pneumonia, (B) C. trachomatis and (C) HSP60 of C. trachomatis in the SpA cohort and healthy controls. The bars represent the medians with IQRs. Only probabilities <0.01 were considered significant and are highlighted in the figure.Back to article page
