question: Compared to GLY 50 μg od, IND 150 μg od, open-label tiotropium (TIO) 18 μg od, and placebo what was the result of indacaterol (IND)/glycopyrronium (GLY) 110/50 μg once daily on forced expiratory volume in 1 second (FEV1)?
context:  IND/GLY showed an improvement in FEV1 AUC5 min–4 h versus all comparators (all P<0.05)
