These changes are most pronounced in asthmatics with frequent exacerbations. http://bit.ly/2wbb8UJWe would like to thank all the participants of the study, and the physicians and research nurses of the Franciscus Gasthuis (Rotterdam, the Netherlands) for their assistance in study design and inclusion of participants.
