“…The current study provides a brief overview of the study and a review and commentary on the main respiratory findings. FEV1 was measured in the original cohort [43] using a Garthur vitalograph (Vitalograph Ltd, Buckingham, UK) (best of two expirations with the subject standing) and in the offspring study using a Fleisch pneumotachograph (with Vitalograph Spirotrac III software, Vitalograph Ltd) and ATS standards to define spirogram acceptability [43,44]. The spirometer's calibration was checked before every session.…”
