BackgroundChronic obstructive pulmonary disease (COPD) has become a huge economic burden. Increasing randomized clinical trials have favored the efficacy of a specified kind of acupuncture-related therapies (ATs) for treating stable COPD. Nonetheless, comparative efficacy of different ATs for stable COPD remains unknown. Thus, the purpose of this network meta-analysis protocol aims to determine the optimal modality of ATs for treating stable COPD.MethodsSix Chinese and English mainstream databases, including PubMed, Cochrane Library, Embase, China Biomedical Literature Database, Chinese National Knowledge Infrastructure, and Wanfang Database, will be systematically retrieved. The time range of the literature search is from the establishment date of each database to July, 2021. The primary outcome measures will be pulmonary function and incidence of acute exacerbations. The secondary outcome measures will consist of 6-minute walking distance, St George's Respiratory Questionnaire, and COPD assessment test. The methodological quality of included studies will be evaluated by Cochrane risk-of-bias tool and the quality of evidence will evaluated through Grading of Recommendations Assessment, Development, and Evaluation instrument. Network meta-analysis will be completed using STATA software.ResultsA synthesis of current evidence of ATs for stable COPD will be provided in this study.ConclusionThis study will contribute to synthesizing the evidence regarding the comparative efficacy of different modalities of ATs for stable COPD. Therefore, it will yield decision-making reference to further assist clinicians in determining the optimal modality of ATs in the treatment of stable COPD.Study RegistrationThis protocol was registered in the international prospective register of systematic reviews (PROSPERO) with the registration number CRD42020166649.Copyright © 2022 the Author(s).
