Fig 1 Predicted relationship between skin prick test result and challenge for peanuts. The logistic regression coefficient was 0.615 (95% CI, 0.411 to 0.818) and constant −1.60 (95% CI, −2.19 to −1.01). The area under the receiver operator curve was 0.86.

Fig 2 Predicted relationship between specific IgE and challenge for peanuts. The logistic regression coefficient was 0.521 (95% CI, 0.328 to 0.713) and constant 0.209 (95% CI, −0.163 to 0.581). The area under the receiver operator curve was 0.77.
