For both cohorts, participants were enrolled consecutively in the pulmonary outpatient clinic and by advertisement between 2016/10/27-2019/11/30. Inclusion criteria were: Age≥18 years, self-reported smoking≥5 cigarettes per day since at least 12 months. Individuals with chronic lung disease, any inhaler medication, or abnormal spirometry defined as FEV1/FVC<0.70 were excluded [9]. The Study was approved by the local ethics committee (KEK BE 246/15, Basec PB 2016-01524; KEK BE 2017-02332); written informed consent was obtained from all participants. Setting: pulmonary outpatient clinic, University Hospital, Bern, Switzerland.FootnotesThis manuscript has recently been accepted for publication in the ERJ Open Research.
