Simple statistics of total number of organ systems in allergic reactions to PNs or TNs and greatest degree of IVS per subject

Each organ system symptom reported received a score of 1. Organ system symptoms included dermatologic (urticaria, pruritus, angioedema, swelling, and worsening of atopic dermatitis), respiratory (wheezing, throat tightness, shortness of breath, cough, and tight chest), gastrointestinal (nausea, vomiting, diarrhea, and abdominal pain), neurological (dizziness and syncope). Degree of IVS was quantified as follows: 0, not reactive (IgE, <0.35 kU/L); 1, WR (IgE, 0.35–0.7 kU/L); 2, MR (IgE, 0.7–3.5 kU/L); 3, HR (IgE, 3.5–17.5 kU/L); 4, VHR (IgE, 17.6–100 kU/L; Quest Diagnostics, Madison, NJ).

HR = highly reactive; IVS = in vitro sensitization; MR = moderately reactive; PN = peanut; TN = tree nut; VHR = very highly reactive; WR = weakly reactive.
