	abstract = {Background: A single long-acting bronchodilator, ultra-long acting muscarinic antagonist (ultra-LAMA) or ultra-long acting β2-agonist (ultra-LABA) is preferred for the initial treatment of patients with chronic obstructive pulmonary disease (COPD); however, there are few head-to-head comparative studies between the two. Here, a meta-analysis of randomized controlled trials was performed to compare the clinical efficacy between ultra-LABA and ultra-LAMA in patients with moderate-to-severe COPD.
Methods: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched (to March 1, 2017) to identify all published randomized controlled trials. 
Results: Of the 12,906 articles found by searching the databases, we obtained data from 10,591 patients with COPD (LABA, n=5,058; LAMA, n=5,533) in seven published studies. Our results showed that COPD exacerbation were significantly lower in patients taking ultra-LAMA than those taking ultra-LABA (odds ratio =0.857, P=0.0008). However, no significant differences were observed between ultra-LAMA and ultra-LABA patients regarding improvement in trough forced expiratory volume in 1 s, the transitional dyspnea index, or St. George’s Respiratory Questionnaire score.
Conclusions: This study suggests that COPD exacerbation occurred less often in patients taking an ultra-LAMA than in those taking an ultra-LABA with similar efficacy of lung function and quality of life.},
