Comparison of pulmonary function tests of usual care (a) and intervention (b) groups of asthmatic patients at the beginning (fine filled bars), middle (medium filled bars) and at the end (coarse filled bars) of a two month study. FEV1: forced expiratory volume in one second; FVC: forced vital capacity; PEF: peak expiratory flow; MMEF: maximal mid expiratory flow; MEF75, MEF50 and MEF25: maximal expiratory flow at 75%, 50%, and 25% of the FVC respectively. All values of PFTs were quoted as percentage predicted. Statistical difference in different parameter between three visits: NS; non significant difference, *; p < 0.05, **; p < 0.01, ***, p < 0.001.
