[Methodological suggestions for the design and implementation of acupuncture Meta-analysis]

As an important approach to secondary research, Meta-analysis provides researchers with a means to supplement evidence. However, though being considered the highest level of evidence, the application of Meta-analysis in acupuncture faces challenges. Despite a substantial number of acupuncture Meta-analyses exists, the varied quality creates the confusion in evidence body. To improve methodological quality, the key issues have been explored in the design, implementation, and reporting of acupuncture Meta-analyses. Before setting up the design, the emphasis should be laid on the prioritization of scientific questions and the feasibility of Meta-analysis methods. During the design, special attention should be given to the development of detailed and transparent methods. In the implementation phase, the importance of researchers' knowledge base and the standardized use of relevant tools should be highlighted. In reporting, the completeness of results should be emphasized, particularly in conclusion formation, with full consideration of evidence quality and clinical significance. The above recommendations of this review aim to provide methodological support for improving the quality of acupuncture Meta-analyses.
