Fig. 5. ROC curve analysis for specific IgE to mugwort pollen, Art v 3, peach and its allergenic components in predicting systemic reactions to peach. Pru p 3-specific IgE had the largest area under ROC curve (AUC, 0.77; 95% CI, 0.676–0.872; P < 0.001) with reference to specific IgE to mugwort pollen (AUC, 0.57; 95% CI, 0.448–0.693; P = 0.271), Art v 3 (AUC, 0.55; 95% CI, 0.420–0.670; P = 0.483), peach (AUC, 0.73; 95% CI, 0.627–0.837; P < 0.001), Pru p 1 (AUC, 0.48; 95% CI, 0.347–0.604; P = 0.701), and Pru p 4 (AUC, 0.58; 95% CI, 0.457–0.708; P = 0.199).

ROC, receiver operating characteristic; IgE, immunoglobulin E; AUC, area under the curve; CI, confidence interval.
