  1. FVC % pred = forced vital capacity expressed as a percentage of predicted; FEV1 % pred = forced expiratory volume in 1 second expressed as a percentage of predicted; FEV1 % VC ref = forced expiratory volume expressed as a percentage of predicted/vital capacity; PEF % pred = peak expiratory flow expressed as a percentage of predicted. GINA classification based on prescribed medication; 1 = intermittent asthma, 2 = persistently mild asthma, 3 = persistently moderate asthma, 4 = persistently severe asthma.
