1 Mite allergen (Der p 1) concentration in houses and its relation to the presence and severity of asthma in a population of Sydney schoolchildren  Guy B. Marks, MBBS, PhD, Euan R. Tovey, PhD, Brett G. Toelle, BApplSc, Susie Wachinger, Jennifer K. Peat, PhD, Ann J. Woolcock, MD  Journal of Allergy and Clinical Immunology  Volume 96, Issue 4, Pages (October 1995) DOI: /S (95) Copyright © 1995 Mosby, Inc. Terms and Conditions

2 FIG. 1 Relative cumulative frequency distribution of mean (over all assessments) concentration of Der p 1 in living room floors (LR, dots), bedroom floors (BR, dash-dot), and beds (BED, long dash) and of the highest concentration in each house (HIGH, solid line). Means are calculated over all assessments. Journal of Allergy and Clinical Immunology  , DOI: ( /S (95) ) Copyright © 1995 Mosby, Inc. Terms and Conditions

3 FIG. 2 Highest mean concentration of Der p 1 in subjects grouped according to the presence of HDM allergy and atopy. The dotted line at 10 μg/gm represents the proposed threshold level of risk for asthma symptoms in subjects allergic to HDM.

4 FIG. 3 Highest mean concentration of Der p 1 in subjects grouped according to the presence of asthma symptoms and airway hyperresponsiveness. The dotted line at 10 μg/gm represents the proposed threshold level of risk for asthma symptoms in subjects allergic to HDM. AHR, Airway hyperresponsiveness.
