To evaluate whether the reporting of search strategies and the primary study selection process in dental systematic reviews is reproducible.
A survey of systematic reviews published in MEDLINE-indexed dental journals from June 2015 to June 2016 was conducted. Study selection was performed independently by two authors, and the reproducibility of the selection process was assessed using a tool consisting of 12 criteria. Regression analyses were implemented to evaluate any associations between degrees of reporting (measured by the number of items positively answered) and journal impact factor (IF), presence of meta-analysis, and number of citations of the systematic review in Google Scholar.
Five hundred and thirty systematic reviews were identified. Following our 12 criteria, none of the systematic reviews had complete reporting of the search strategies and selection process. Eight (1.5%) systematic reviews reported the list of excluded articles (with reasons for exclusion) after title and abstract assessment. Systematic reviews with more positive answers to the criteria were significantly associated with higher journal IF, number of citations, and inclusion of meta-analysis.
Search strategies and primary study selection process in systematic reviews published in MEDLINE-indexed dental journals may not be fully reproducible.
评估口腔系统评价中检索策略和主要研究选择过程的报告是否具有可重复性。
对 2015 年 6 月至 2016 年 6 月发表在 MEDLINE 索引的口腔期刊上的系统评价进行了调查。两名作者独立进行研究选择，使用包含 12 个标准的工具评估选择过程的可重复性。实施回归分析以评估报告程度（通过回答的项目数来衡量）与期刊影响因子（IF）、是否存在荟萃分析以及系统评价在 Google Scholar 中的引用次数之间的任何关联。
共确定了 530 篇系统评价。根据我们的 12 个标准，没有一篇系统评价完整报告了检索策略和选择过程。8 篇（1.5%）系统评价在标题和摘要评估后报告了排除文章的列表（包括排除原因）。对标准有更多正面回答的系统评价与更高的期刊 IF、引用次数和荟萃分析的纳入显著相关。
发表在 MEDLINE 索引的口腔期刊上的系统评价中的检索策略和主要研究选择过程可能无法完全重现。
