Evaluating triple ICS/LABA/LAMA therapies for COPD patients: a network meta-analysis of ETHOS, KRONOS, IMPACT, and TRILOGY studies
In some studies comparing triple with dual combination therapies in COPD there might be a possible effect of inhaler bias resulting from different inhaler devices being used in comparator arms. The aim of this study was a quantitative synthesis by considering the studies that directly compared triple ICS/LABA/LAMA vs. either dual LABA/LAMA or ICS/LABA therapies …
