ROC curves for the most discriminative characteristics, allowing for comparison, in the subpopulation of n = 60, initially selected for avidity analyses. Displayed are ROC curves for peanut-sIgE (purple), Ara h 2 sIgE (orange), Ara h 6 sIgE (blue), peanut SA (red), Ara h 2 SA (yellow), Ara h 6 SA (turquoise), avidity (pink), PD (light green), and WD (gray). For corresponding areas under the curves, see Table E4.
