WebThe predicted values of FEV 1 and FVC were calculated from the Global Lung Function Initiative equations . Various lung function states on the basis of FEV 1 z-scores were determined as five parallel states (i.e., very high, high, normal, low, and very low groups). WebThe mean FEV 1 of the cohort studied was 92.7% of predicted, with 77% of the values within the normal range (>80% of predicted). In contrast, the mean FEF 25–75 was 78% with only 27.7% of the values greater than 80% of predicted, while 30.4% were between 60% and 80%, and 40.9% were less than 60% of predicted.
