Efficacy and safety of modified Yupingfeng formula in treating allergic rhinitis: A protocol for systematic review and meta analysis

Abstract

Background:Allergic rhinitis (AR) is a non-infectious chronic nasal mucosal disease mediated mainly by IgE, which affects 40% of the global population and has a recurrence rate of more than 50%. The modified Yupingfeng formula (MYPFF) is widely used in the treatment of allergic rhinitis in China. However, there is no evidence-based medical evidence for the efficacy and safety of MYPFF in the treatment of allergic rhinitis.Methods:Database as China National Knowledge Infrastructure, Chinese Biomedical Literature Database, Chinese Scientific Journal Database (VIP database), Wan-Fang Database, the Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, EMBASE, and Web of Science will be searched for relevant literature from inception to September 2020. Data extraction will be performed on the obtained literature. Then RevMan V.5.3 will be used for the assessment of the risk of bias and data synthesis.Results:The results will be published in a peer-reviewed journal.Conclusion:The conclusion of the study will provide an evidence to efficacy and safety of MYPFF in treating allergic rhinitis, which will be of significant meaning for further research and clinical practice.OSF registration number:10.17605/OSF.IO/RV9P4.
