  1. Besides FEV1/FVC for which ratio values are given, lung function variables are expressed in % of predicted values. Data are reported as mean ± SD. HRmax: maximal heart rate obtained during the maximal incremental test, \(\dot{\text{V}}\)̇Emax: maximal voluntary ventilation achieved during the maximal incremental test, \(\dot{\text{V}}\)E: ventilation, p: comparison between atopic and non-atopic subjects
