Fig. 3From: Development and validation of a competitive ELISA based on virus-like particles of serotype Senecavirus A to detect serum antibodiesValidation of cELISA by ROC curve (a). The PI values of 104 confirmed sera calculated by cELISA were compared with the virus neutralization test results via ROC analysis. AUC stands for area under curve. The value of sensitivity or specificity of the cELISA calculated at varied cutoff value (b)Back to article page
