| Conclusions Once-daily UMEC/VI significantly improved lung function vs twice-daily FSC 250/50mcg in moderate-to-severe COPD patients with infrequent COPD exacerbations Both treatments improved dyspnea and QoL Overall, the AE incidence was similar between treatment groups These findings suggest that treatment with UMEC/VI provides greater lung function benefits than FSC in moderate-to-severe COPD patients with infrequent COPD exacerbations
