Fig. 1. The receiver operating characteristics (ROC)-curve predicting probability to have positive challenge test. A typical ROC curve for predicting month-1 challenge test result based on the change in Cow's Milk-related-Symptom-Score (CoMiSS™) from baseline to month-1 and based on data generated to cover the entire range of the CoMiSS™ (0-12). The area under the curve (AUC) of the ROC curve is 0.88. The thin straight line depicts random prediction with an AUC of 0.5.
