Predicted probabilities of baked egg challenge outcome. A–C, Estimated probability curves for failing oral baked egg challenge at a given egg white sIgE (n = 161), ovomucoid sIgE (n = 162), or egg white SPT (n = 147) level derived from logistic regression. Blood and SPT results were obtained within 1 year before challenge date. Open circles represent individual subjects. Shaded regions indicate 95% confidence limits. D, ROC curves show the performance of egg white sIgE, ovomucoid sIgE, and egg white SPT in relation to baked egg challenge outcome. No significant difference was observed among the AUCs (P = .301).
