Table 2 Air pollution exposure averaged over 3, 24 and 120 h before FeNO measurement, based on measurements from a central monitoring station 2001–2008. Distribution of exposures estimated in the study population (mean, quantiles). All units µg/m3
From: Genetic susceptibility to airway inflammation and exposure to short-term outdoor air pollution
