ROC curves used to determine cut-off and AUC values for the six recombinant antigens tested in total IgG ELISA against sera from group I and from healthy individuals. The calculated cut-offs and AUCs are presented in Table 1. Source of the curve: Black lines: —, reference line; – – –, AgB8/2; ·· ·, AgB8/1; ·· – – · ·, EgcMDH; Grey lines: –– –, EgCaBP2; ·· ·, EgAFFPf; ·· – – · ·, EgAFFPt.
