1 Early childhood IgE reactivity to pathogenesis-related class 10 proteins predicts allergic rhinitis in adolescence  Marit Westman, MD, Christian Lupinek, MD, Jean Bousquet, MD, PhD, Niklas Andersson, MSc, Sandra Pahr, MSc, Alexandra Baar, PhD, Anna Bergström, PhD, Mats Holmström, MD, PhD, Pär Stjärne, MD, PhD, Karin C. Lødrup Carlsen, MD, PhD, Kaj-Håkon Carlsen, MD, PhD, Josep M. Antó, MD, PhD, Rudolf Valenta, MD, PhD, Marianne van Hage, MD, PhD, Magnus Wickman, MD, PhD  Journal of Allergy and Clinical Immunology  Volume 135, Issue 5, Pages e11 (May 2015) DOI: /j.jaci Copyright © 2014 American Academy of Allergy, Asthma & Immunology Terms and Conditions

2 Fig 1 A, Prevalence of IgE reactivity to PR-10 proteins in the population (≥0.3 ISU-E). B, Specific IgE levels to the different PR-10 proteins among sensitized children (≥0.3 ISU-E), where boxes show the median levels and 25th and 75th percentiles at 4, 8, and 16 years of age, respectively.

3 Fig 2 Number of children with IgE-reactivity to the different PR-10 proteins (left column) and percentages with additional IgE-reactivity to other PR-10 proteins. Green, High degree of IgE cross reactivity; Red, low degree of IgE cross reactivity.

4 Fig 3 Proportional Venn diagram of numbers of children who reported symptoms after exposure to birch pollen from the upper and lower airways, respectively, and IgE reactivity to Bet v 1 at 4 (n = 764), 8 (n = 763), and 16 (n = 686) years of age.

5 Fig 4 Probabilities for incident or persistent ARbp from 4 to 16 years of age in relation to Bet v 1–specific IgE levels (ISU-E) at 4 and 8 years of age, respectively.

6 Fig 5 Bet v 1–specific IgE levels (ISU-E) at age 4 years among children with mild ARbp compared with those with moderate/severe ARbp at 16 years of age, with box plots showing median levels and 25th and 75th percentiles.

8 Fig E2 Cross-sectional probabilities to report ARbp at 4, 8, and 16 years of age in relation to levels of specific IgE to birch (measured with ImmunoCAP) among all children in the BAMSE cohort, the 1699 children with blood samples from all 3 time points, and the study population.
