Systematic reviews (SRs) and/or meta-analyses of research have an important role in establishing the foundation for clinical studies. In this study, we aimed to evaluate the reporting quality of SRs of studies using the PRISMA checklist. Four databases were searched including PubMed, Virtual Health Library (VHL), Web of Science (ISI) and Scopus. The search was limited from 2006 to 2016 to include all SRs and/or meta-analyses (MAs) of pure studies. The evaluation of reporting quality was done using the PRISMA checklist. Out of 7702 search results, 65 SRs were included and evaluated with the PRISMA checklist. Overall, the mean overall quality score of reported items of the PRISMA checklist was 68%. We have noticed an increasing pattern in the numbers of published SRs of studies over the last 10 years. In contrast, the reporting quality was not significantly improved over the same period ( = .363). There was a positive but not significant correlation between the overall quality score and the journal impact factor of the included studies. The adherence of SRs of studies to the PRISMA guidelines was poor. Therefore, we believe that using reporting guidelines and journals paying attention to this fact will improve the quality of SRs of studies.
系统评价（SRs）和/或研究的荟萃分析在为临床研究奠定基础方面具有重要作用。在这项研究中，我们旨在使用 PRISMA 清单评估研究的 SRs 的报告质量。共检索了 4 个数据库，包括 PubMed、虚拟健康图书馆（VHL）、科学引文索引（ISI）和 Scopus。搜索范围限于 2006 年至 2016 年，以纳入所有纯研究的 SRs 和/或荟萃分析（MA）。使用 PRISMA 清单评估报告质量。在 7702 个搜索结果中，有 65 项 SR 被纳入并使用 PRISMA 清单进行评估。总体而言，PRISMA 清单报告项目的平均整体质量评分是 68％。我们注意到，在过去 10 年中，发表的研究的 SRs 数量呈增加趋势。相比之下，同一时期的报告质量并没有显著提高（ = .363）。整体质量评分与纳入研究的期刊影响因子之间存在正相关关系，但不显著。研究的 SRs 对 PRISMA 指南的遵循情况较差。因此，我们认为使用报告指南和期刊关注这一事实将提高研究的 SRs 质量。
