5 Fig 4 A, Representative illustration of digital 3-dimensional time-lapse photographic images of cold-induced wheal responses over time in 1 patient with ACU after treatment with placebo, 5 mg/d desloratadine, and 20 mg/d desloratadine for 7 days. B, Example of thermographic images of the cold-induced wheal response over 20 minutes in a patient with ACU treated with placebo, 5 mg/d desloratadine, and 20 mg/d desloratadine for 7 days.

6 Fig 5 A, Box and whisker plots showing the wheal volume 15 minutes after cold provocation testing and after treatment with placebo (mean, mm3 [SD, mm3]), 5 mg of desloratadine (mean, mm3 [SD, mm3]), and 20 mg of desloratadine (mean, mm3 [SD, mm3]) every day for 7 days. Circles within the figures represent outlayers, and triangles illustrate extreme values. B, Mean wheal volume AUC over 90 minutes after cold provocation after treatment with placebo (mean, mm3 (SD, mm3]), 5 mg of desloratadine (mean, mm3 [SD, mm3]), and 20 mg of desloratadine (mean, mm3 [SD, mm3]) every day for 7 days. DL, Desloratadine. ∗∗∗P ≤ .001. Journal of Allergy and Clinical Immunology  , DOI: ( /j.jaci ) Copyright © 2009 American Academy of Allergy, Asthma & Immunology Terms and Conditions

7 Fig 6 A, Box and whisker plots showing the CTTs elicited by using cold provocation at baseline and after treatment with placebo, 5 mg of desloratadine, and 20 mg of desloratadine every day for 7 days (assessed 10 minutes after provocation). B, CSTTs elicited by using cold provocation at baseline and after treatment with placebo, 5 mg of desloratadine, and 20 mg of desloratadine every day for 7 days. Circles within the figures represent outlayers, and triangles illustrate extreme values. DL, Desloratadine. ∗∗P ≤ .01; ∗∗∗P ≤ .001 (assessed 10 minutes after provocation).
