The table above illustrates the values for the 5 spirometry variables for each subject, (FEV1, FEV1 [%Pred] FVC, FVC [%Pred] and FEV1/FVC) as well as the six-minute walking test (6MWT).
Median values are displayed in bold, minimum and maximum range in square brackets. Curly braces {} denote the overall trend of the variable throughout the study: ↑, trend increased; ↓ trend decreased; →, no change in trend. FEV1, Forced Expiratory Volume in the first second (Litres); FVC, Forced Vital Capacity, (Litres); NA, result not available.
