Extract
With great interest we read the article by Arshad et al. [1] and the accompanying editorial [2] in the March 2020 issue of the European Respiratory Journal. We fully agree that early detection and small airway function are both of utmost importance for the management of obstructive lung disease. However, we have some methodological concerns in this context. These should be discussed as certain imitations of the important work at hand.
Abstract
Small airway function comprises heterogenous interactions between ventilation, diffusion, perfusion and inflammation that cannot be covered by spirometry https://bit.ly/2LiyQ5E
