Background: Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease with high morbidity and mortality worldwide. Jianpi Yiqi method (JYM) is a classical Chinese therapy in the treatment of COPD. However, there is no systematic review related to JYM for COPD. In this study, we aim to systematically examine the efficacy and safety for clinical use of JYM.
Methods and analysis: We will conduct a comprehensive retrieval in the following electronic databases: PubMed, Embase, MEDLINE, Cochrane Library Central Register of Controlled Trials, China National Knowledge Infrastructure (CNKI) database, Wanfang Data Knowledge Service Platform, Chinese Scientific Journals Database (VIP), Chinese Biomedical Literature Service System (SinoMed), and other sources. Two trained reviewers will identify relevant studies, extract data information, and then assess the methodical quality by the Cochrane risk of bias assessment tool, independently. Then the meta-analyses will be conducted by using the RevMan 5.2. Based on the heterogeneity test, data integration is performed using a fixed effect model or a random effects model. A sensitivity analysis will be performed to evaluate the stability of the results. Then publication bias assessment will be conducted by funnel plot analysis and Egger test. Finally, the quality of evidence will be assessed by the GRADE system.
Results: The results of our research will be published in a peer-reviewed journal.
Conclusion: The conclusion of our systematic review will provide evidence to judge whether JYM is an effective intervention for patients with COPD.
