Review Meta Analysis Comparative StudyBudesonide/formoterol vs. salmeterol/fluticasone in COPD: a systematic review and adjusted indirect comparison of pneumonia in randomised controlled trials.
This analysis was designed to provide a comparison between budesonide/formoterol and salmeterol/fluticasone for the relative incidence of pneumonia adverse events, pneumonia serious adverse events and pneumonia-related mortality in patients being treated for chronic obstructive pulmonary disease. ⋯ The results of the indirect comparison support the hypothesis that budesonide/formoterol is associated with fewer pneumonia events than salmeterol/fluticasone in chronic obstructive pulmonary disease. The limitations of the analysis are that the results from a single study, TORCH, have a large bearing on the overall findings of the analysis, and that there is heterogeneity in the length and the dosing of the included studies, although it does not appear that heterogeneity affected the reported results. Another important limitation is the lack of predefined diagnostic standards for pneumonia in these studies.
