1 Specific IgE and IgG measured by the MeDALL allergen-chip depend on allergen and route of exposure: The EGEA study  Valérie Siroux, PhD, Christian Lupinek, MD, Yvonne Resch, PhD, Mirela Curin, PhD, Jocelyne Just, MD, PhD, Thomas Keil, MD, MSc, Renata Kiss, PhD, Karin Lødrup Carlsen, MD, PhD, Erik Melén, MD, PhD, Rachel Nadif, PhD, Isabelle Pin, MD, Ingebjørg Skrindo, PhD, Susanne Vrtala, PhD, Magnus Wickman, MD, PhD, Josep Maria Anto, MD, PhD, Rudolf Valenta, MD, PhD, Jean Bousquet, MD, PhD  Journal of Allergy and Clinical Immunology  Volume 139, Issue 2, Pages e6 (February 2017) DOI: /j.jaci Copyright © 2016 American Academy of Allergy, Asthma & Immunology Terms and Conditions

2 Fig 1 IgE and IgG recognition frequencies and intensities for genuine pollen marker allergens from ragweed (Amb a 1) (A), birch (Bet v 1) (B), cypress (Cup a 1) (C), olive/ash (Ole e 1) (D), and timothy grass (Phl p 1) (E) and for cross-reactive pollen allergens timothy grass polcalcin (Phl p 7) (F), birch polcalcin (Bet v 4) (G), timothy grass profilin (Phl p 12) (H), and birch profilin (Bet v 2) (I), and for the Bet v 1–related food allergen from apple (Malus domestica 1) (J) in different regions of France. Shown are the percentages of subjects (y-axes) with IgE (upper panels) and IgG reactivity (middle panels) to the allergens in the different cities of France (x-axes) and the pollen counts in the different areas of France (lower panels). Antibody levels are color-coded and shown in ISU. P values assessing the differences across centers were estimated from the nonparametric Kruskal-Wallis test.
