Interactive dot diagram for detection of H7 antibodies in chicken (a), duck (b) and peacock (c) sera and ROC curves for detection of H7 antibodies in chicken (d), duck (e) and peacock (f) sera used to set the cut-off values for the cELISA immunoassay. Each dot represents one serum sample. The horizontal dotted lines indicate the optimal cut off levels with the best sensitivity and specificity. AUC represents area under the curve
