Estimation and comparison of the Dn and Dp values of the assay by analyzing the receiver operating characteristic (ROC) curve. a Interactive dot diagram of the VP2-epitp-ELISA in testing sera from swine: 0, negative serum samples (n = 102) from clinically healthy and unvaccinated animals; 1, positive serum samples (n = 124) from vaccinated animals. Each point on the dot diagram represents a serum sample with a known statue, and associated with a particular PP value. b Each point on the ROC plot represents a sensitivity-specificity pair associated with a particular threshold. The best Dn and Dp values were 91.13% and 91.17%, respectively, and the criterion was 37%
