Figure 5

Mean values of a) FEV1, b) FVC and c) the Ratio expressed as percent of predicted according to different reference values, by sex. Mean percent of predicted values are displayed for FEV1, FVC and the FEV1/FVC and FEV1/VC ratios based on data from a population-based sample of healthy non-smoking subjects. The age-span included is 22 to 65 years (n=192 women and n=218 men) in which all reference values can be applied without extrapolation. GLI=Global Lung Initiative 2012, ECSC=European Coal and Steel Community. *p-value<0.05 (one-sample T-test compared to 100%). ¤ Berglund reference values for FVC represent VC; i.e. the best of FVC and SVC.
