Moxibustion for anorexia in COVID-19: A protocol for systematic review and meta-analysis

BACKGROUND: As the outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly spread over the world, the World Health Organization has declared the outbreak of COVID-19 an international public health emergency. Besides typical respiratory symptoms and signs of COVID-19, digestive symptoms and liver injury have been frequently reported during the course of the disease. The purpose of this study was to evaluate the efficacy and safety of moxibustion in the treatment of anorexia in patients with COVID-19. METHODS: According to the retrieval strategies, randomized controlled trials on moxibustion therapies for C19-A will be obtained from the China National Knowledge Infrastructure, WanFang Data, Chinese Scientific Journals Database, PubMed, Embase, and Cochrane Library, regardless of publication date or language. Studies will be screened based on inclusion and exclusion criteria, and the Cochrane risk bias assessment tool will be used to evaluate the quality of the literature. The network meta-analysis will be performed with the Markov chain Monte Carlo method and carried out with Stata 14.2 and WinBUGS 1.4.3 software. Ultimately, the quality of the evidence obtained from the results will be evaluated. RESULTS: This study will evaluate whether moxibustion therapy can effectively treat anorexia in patients with COVID-19. CONCLUSION: This study will provide evidence for whether moxibustion therapy is beneficial to the treatment of anorexia in patients with COVID-19. TRIAL REGISTRATION NUMBER: CRD42022302499
