AB  - In Northern Europe, the prevalence of asthma differs between countries, but an objective clinical comparison of bronchial inflammation is missing. Therefore, we aimed to study the fractional exhaled nitric oxide FENO, a biomarker of airway inflammation, in population samples of the general populations of Sweden, Finland and Estonia. We further aimed to analyse methodological and physiological features of FENO acquisition, such as mouthwashes and dependency of expiratory flow. 

We performed cl...
