Data are presented as mean±sd, unless otherwise stated. FEV1: forced expiratory volume in one second; FVC: forced vital capacity; PEF: peak expiratory flow; MEF50%: mid-expiratory flow at 50% vital capacity; BDP/F: beclomethasone/formoterol; BUD/F: budesonide/formoterol. The p-values refer to comparison between groups in final values (week 12, last visit). #: mean changes from baseline (intention-to-treat population)
