Since there is no consistent evidence on the effectiveness of acupuncture in the treatment of mild cognitive impairment, this review aims to summarize and critically evaluate the methodological and reporting quality of systematic reviews (SRs).
We comprehensively searched PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Chinese Biomedical Literature (CBM), and Wanfang databases from the date of establishment to April 2019. Two authors independently selected the articles, collected the data, and assessed the identified and included SRs with the revised measurement tool to assess systematic reviews (AMSTAR 2) and preferred reporting items for SRs and meta-analyses (PRISMA). The quality of outcomes was evaluated by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE).
Eleven SRs were included in this overview. The items of AMSTAR 2 in most SRs were poorly reported; only 3 SRs were rated as low quality by AMSTAR 2, and the remaining were rated as very low quality. A total of 8 SRs obtained a decent rating by PRISMA. With the GRADE tool, we have not found high-quality evidence that acupuncture is effective for mild cognitive impairment (MCI), so there is no certain conclusion on the effectiveness of acupuncture treatment for MCI.
The methodological and reporting quality of SRs on acupuncture for MCI is substandard, and the quality of evidence is poor. In future research, more efforts are needed to improve the quality of SRs in this field.
由于针刺治疗轻度认知障碍的有效性尚无一致证据，本综述旨在总结并批判性评价系统评价（SRs）的方法学和报告质量。
我们全面检索了PubMed、Embase、Cochrane图书馆、Web of Science、中国知网（CNKI）、维普中国科技期刊数据库（VIP）、中国生物医学文献数据库（CBM）和万方数据库，检索时间从建库至2019年4月。两位作者独立筛选文章、收集数据，并使用修订后的系统评价测量工具（AMSTAR 2）和系统评价与Meta分析的首选报告项目（PRISMA）对纳入和识别出的SRs进行评估。结局质量采用推荐意见分级、评估、制定与评价（GRADE）进行评价。
本综述纳入了11项SRs。大多数SRs中AMSTAR 2的条目报告不佳；只有3项SRs被AMSTAR 2评为低质量，其余被评为极低质量。共有8项SRs在PRISMA中获得了不错的评分。使用GRADE工具，我们未发现高质量证据表明针刺对轻度认知障碍（MCI）有效，因此针刺治疗MCI的有效性尚无定论。
关于针刺治疗MCI的SRs的方法学和报告质量不达标，证据质量较差。在未来研究中，需要更多努力来提高该领域SRs的质量。
