Fig 6. Two-dimensional serodiagnostic profile of all samples from SKI cases according to levels of IgA-Ptx and IgG-Ptx.

Fig 6

Blue circles and red triangles represent retrospective and convalescent cases respectively. Grey dotted line represents 62.5 IU/ml IgG-Ptx cut-off. Black dotted lines represent model based cut-offs at 10.5 IU/ml and 104 IU/ml for IgA-Ptx and IgG-Ptx respectively. Samples are divided in 4 quadrants; QI: IgG-PtxloIgA-Ptxhi, QII: IgG-PtxhiIgA-Ptxhi, QIII: IgG-PtxhiIgA-Ptxlo, QIV: IgG-PtxloIgA-Ptxlo. m = months.
