Abstract
BACKGROUND: Allergic rhinitis (AR) is one of the most common allergic disorders globally. Several systematic reviews and meta-analyses have reported the effectiveness of acupuncture for patients with AR. However, the evidence has not been systematically synthesized. This overview aims to map, synthesize, and assess the reliability of evidence generated from these systematic reviews (SRs) and meta-analyses of acupuncture for AR. METHODS: A Comprehensive literature search will be conducted through the PubMed, Embase, the Cochrane Library of Systematic Reviews, the China National Knowledge Infrastructure Database, Wanfang Database, Chinese Biomedical Literature Database, and Chinese Scientific Journal Database from inception until January 2020. Additionally, the PROSPERO database and the reference list of included studies will be searched for unpublished, ongoing, or recently completed SRs and meta-analyses. The reviewers will identify reviews independently and extract data according to the methodological guidelines for overviews provided by the Cochrane Collaboration. The risk of bias will be assessed based on the Risk of Bias in Systematic Reviews. The methodological and reporting quality of the included reviews will be assessed using the Assessing the Methodological Quality of Systematic Reviews (V.2) tool and the Preferred Reporting Items for Systematic Review and Meta-Analyses statement. The outcomes of interest include total nasal symptom score, rhinoconjunctivitis quality-of-life questionnaire, immunoglobulin E, visual analog scale, laboratory examination, and side effects. The quality of evidence of outcomes will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation. The evidence will be synthesized where appropriate based on patient subgroups and outcomes. ETHICS AND DISSEMINATION: Ethical approval is not required for overviews. We plan to publish results in peer-reviewed journals and present at international and national academic, clinical, and patient conferences. RESULTS: The results will be published in a peer-reviewed journal. CONCLUSION: This overview will provide comprehensive evidence of acupuncture for patients with AR.
