From: Major comorbid conditions in asthma and association with asthma-related hospitalizations and emergency department admissions in adults: results from the German national health telephone interview survey (GEDA) 2010

Characteristics Unweighted n Weighted % (95%-CI)

History of allergic rhinitis 678 54.5 (50.6-58.3)
Current allergic rhinitis (in the past year) 535 42.3 (38.6-46.0)
Current GERD-like symptoms (in the past year) 522 49.6 (45.8-53.4)
History of AERD 138 14.0 (11.3-17.2)
History of nasal polyps 350 29.8 (26.5-33.4)
- among AERD cases 57 36.9 (26.9-48.2)
- among non-AERD cases 287 28.3 (24.8-32.1)
History of AERD and nasal polyps (Samter’s triad) 57 5.2 (3.7-7.3)
Study outcome   
Any vs. no asthma-related hospitalization/emergency department admission in the past year 96 9.0 (7.1-11.5)
  1. Weighted prevalence (%) with 95% confidence interval (95%-CI), unweighted count (n). Unknown or missing responses excluded from the analyses. % (n) of missing values for outcome study variable are as follows: any asthma-related hospitalization/emergency department admission in the past year 0.1% (n = 2) missing values. % (n) of missing values for primary independent study variables are as follows: current AR 1.1% (n = 15), current GERS 0.3% (n = 6), and AERD 1.2% (n = 12). Gastroesophageal reflux disease (GERD); acetylsalicylic acid exacerbated respiratory disease (AERD).
