Defining and grading an obstructive ventilatory defect (OVD): ‘FEV(1)/FVC lower limit of normal (LLN) vs. Z-score’ and ‘FEV(1) percentage predicted (%pred) vs. Z-score’

An obstructive ventilatory defect (OVD) is defined by a low forced expiratory volume/‘forced/slow’ vital capacity (FEV(1)/FVC) (e.g. <lower limit of normal (LLN)). However, the LLN can be estimated either by the 90% confidence interval (or the 90th percentile) (American Thoracic and the European...
