Fig. 3From: Development and evaluation of a monoclonal antibody-based competitive ELISA for the detection of antibodies against H7 avian influenza virusInteractive 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 curveBack to article page
