Fig. 3.

Specific IgG antibody levels in sera of patients with different stages of cystic echinococcosis (CE) and alveolar echinococcosis (AE) and those from healthy controls (NH) against rEgAgB1-5. The Y-axis displays absorbance values of detected sera. The X-axis indicates the following sera groups: CE1 (n = 26); CE2 (n = 19); CE3 (n = 30; 10 and 20 samples of CE3a and CE3b, respectively); CE4 (n = 22); CE5 (n = 13); AE (n = 12); and NH (n = 62). The cut-off values for respective rEgAgBs are determined by receiver operating characteristic (ROC) analysis (red dotted lines). Horizontal blue bars denote average specific antibody levels in each group
