None of the patients required oxygen supplementation, and only one patient had asthma. Patients who had received ventilator therapy during infancy had significantly lower maximal instantaneous forced expiratory flow (MEF%) (66%; 43\u201393% vs 105%; 63\u2013110%; p=0.048) and forced expiratory volume\/forced vital capacity (0.76; 0.7\u20130.81 vs 0.89; 0.77\u20130.91; p=0.03) than patients without a history of mechanical ventilation, suggesting tendency for airway obstruction in the former group of patients.
