Levocetirizine better protects than desloratadine in a nasal provocation with allergen  Cédric Deruaz, MD, Annette Leimgruber, MD, Monika Berney, Estelle Pradervand, François Spertini, MD  Journal of Allergy and Clinical Immunology  Volume 113, Issue 4, Pages 669-676 (April 2004) DOI: 10.1016/j.jaci.2004.01.773

Fig 1 Cumulative number of patients reaching the global threshold according to the dose level of grass pollen allergen. Inset, Difference (Δ) in allergen dose level necessary to reach the threshold for each of the 24 patients between levocetirizine and desloratadine (in favor of levocetirizine, >0; in favor of desloratadine, <0). Plain vertical line, Mean Δ allergen dose level. Journal of Allergy and Clinical Immunology 2004 113, 669-676DOI: (10.1016/j.jaci.2004.01.773)

Fig 2 Cumulative number of patients reaching the threshold according to the dose level of grass pollen allergen (X axis) for sneezes (A), secretions (B), PNIF (C), and MCA (D). In Fig 2, C and D, 24H corresponds to the 24-hour time point after the NPT. Insets, results are expressed as described in Fig 1.
