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 (FEV1) (PC20), 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
