Data are presented as arithmetic mean±sem
Geometric mean±sem is given for immunoglobulin (Ig)E. For provocative concentration causing a 20% fall in forced expiratory volume in one second (FEV_{1}) (PC_{20}), eosinophils, tryptase and exhaled nitric oxide (NO), geometric mean±sem (to be understood as a variability factor, indicated by ÷) are supplied
FVC: forced vital capacity
% pred: % predicted
Mch: Methacholine
ppb: parts per billion
Concentration of exhaled NO at a flow rate of 50 mL·s^{−1} as interpolated from values obtained at four different flow rates
