1 Dose-time-response relationship in peanut allergy using a human model of passive cutaneous anaphylaxis  Anja P. Mose, MD, Charlotte G. Mortz, MD, PhD, Esben Eller, MSc, PhD, Ulrik Sprogøe, MD, PhD, Torben Barington, MD, DMSci, Carsten Bindslev-Jensen, MD, PhD, DMSci  Journal of Allergy and Clinical Immunology  Volume 139, Issue 6, Pages e4 (June 2017) DOI: /j.jaci Copyright © 2017 American Academy of Allergy, Asthma & Immunology Terms and Conditions

2 Fig 1 The number of reacting recipients (gray bars) and the median Treact (●/erythema and o/wheal) in relation to the level of sIgE. The study includes 10 recipients sensitized with serum from donor 2 (Table E1) in 5 increasing concentrations. The oral peanut challenges were carried out as single dose (10 g of whole peanut).

3 Fig 2 A, The median Treact in relation to the challenge dose. B, The median Swheal in relation to the challenge dose. Both graphs (box plots) display the distribution of the data as follows: the median, the 25th and 75th percentiles (the boundary of the box), and the highest and lowest values (the whiskers above and below the box). All recipients were sensitized with donor serum 2, 3, and 4 (Table E1). The difference in the median Treact between all doses compared pairwise was statistically significant (P ≤ .003) except for the difference between 1 g and 3 g of peanut (P = .4). The difference in the median Swheal between the doses compared pairwise was statistically significant (P ≤ .001) except for the differences between 1 g and 3 g of peanut (P = .05) and 10 g and 100 g of peanut (P = .1). The asterisks indicate that a reaction was negative.

5 Fig E2 Open titrated oral peanut challenges. The study includes 14 recipients sensitized with serum from donor 2. The challenge doses of peanut were administered at 1-hour intervals.
