Figure 3. Predicted Probabilities for Almond-specific IgE (A) and Almond SPT (B) and ROC Analysis of Almond SPT, Almond specific IgE, and age at challenge in predicting Challenge Outcome (C) and IgE-mediated reactions (D).
Almond SPT of 46 mm and almond-specific IgE of 174 kU/L were associated with 95% predicted probability of failing a challenge (A & B, dashed black line). Almond SPT of 36 mm and almond-specific IgE of 166 kU/L were associated with 95% predicted probability of having an Grade 2/3 allergic reaction during a challenge (A & B, solid line).
