Background:
The ability to exercise is an important clinical outcome in COPD, and the improvement in exercise capacity is recognized to be an important goal in the management of COPD. Therefore, since the current interest in the use of bronchodilators in COPD is gradually shifting towards the dual bronchodilation, we carried out a meta-analysis to evaluate the impact of LABA/LAMA combination on exercise capacity and lung hyperinflation in COPD.
Methods:
RCTs were identified after a search in different databases of published and unpublished trials. The aim of this study was to assess the influence of LABA/LAMA combinations on endurance time (ET) and inspiratory capacity (IC), vs. monocomponents.
Results:
Eight RCTs including 1632 COPD patients were meta-analysed. LABA/LAMA combinations were significantly (P < 0.05) more effective than the LABA or LAMA alone in terms of the improvement in ET (+43 s and +22 s, respectively) and IC (+107 ml and +87 ml, respectively). LABA/LAMA combinations showed the highest probability of being the best therapy with regard of both ET and IC (100% and 100%, respectively), followed by LAMA (66% and 64%, respectively) and LABA (32% and 36%, respectively), as indicated by the analysis of surface under the cumulative ranking curve (SUCRA). No publication bias was detected in this meta-analysis.
Conclusions:
This meta-analysis clearly demonstrates that if the goal of the therapy is to enhance exercise capacity in patients with COPD, LABA/LAMA combinations consistently meet the putative clinically meaningful differences for both ET and IC and, in this respect, are superior to their monocomponents.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
01:25Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
