Fig. 3. Results obtained for the case and control groups along with ROC curves for each quantitative assay. (A) The gray bars represent regions containing borderline results. The triangle represents a result above the measurement range of the ELISA rBio. (B) Sensitivity is plotted on the Y-axis and 1–specificity is plotted on the X-axis. The gray tick marks on the ROC curve represent the upper and lower cut-offs recommended by the respective manufacturer. Squares mark the cut-offs with the highest Youden’s indices.
Abbreviation: AUC, area under the curve.
