Comparison of two different pollen season definitions based on 10 years of birch and grass pollen data from two distant central European cities: An EAACI Task Force report.

The article compares two different methods of defining pollen seasons based on 10 years of birch and grass pollen data from Berlin, Germany, and Vienna, Austria. The study found that the European Academy of Allergy and Clinical Immunology (EAACI) definition correlated significantly with allergic rhinitis symptoms reported by users of electronic diaries. The analysis showed differences in the start, end, and duration of pollen seasons between the two cities, highlighting the importance of accurately defining pollen seasons for clinical trials and allergen immunotherapy. The study confirmed the applicability of both the EAACI and percentage analysis (PA) methods in describing pollen season characteristics for different regions. [Extracted from the article]
