BACKGROUND This scoping review aims to identify, review and characterize the published recommendations to conduct and/or to report a systematic review in medical interventions area. METHODS A search was carried out in PubMed, EMBASE and Cochrane Library databases, using systematic reviews search filters. The search comprises all recommendations to conduct and/or report a systematic review. Data on methods were extracted from each recommendation. A descriptive analysis was performed. RESULTS Eighty-three recommendations were identified. Approximately 60% of retrieved references were published in the last 6 years. Recommendations to both conduct and report a systematic review were issued in 47% studies. The guidance presented in each recommendation to conduct and/ or report a systematic review varied. Almost 96% of the recommendations offer guidance on systematic review methods section. The need and time for updating was only recommended in 29% of recommendations. Forty percent of recommendations endorsed their methods to any subject related to medical interventions. Half of the studies did not specify the design of studies to be included in a systematic review. CONCLUSIONS Several recommendations to conduct and/or report a systematic review were published and offered different guidance. Further research on the impact of such heterogeneity can improve systematic reviews quality.

在医学文献中进行和报告系统评价的建议：范围界定评价。

背景技术这种范围审查旨在识别，审查和表征已发表的建议，以在医疗干预领域进行和/或报告系统的审查。方法使用系统评价搜索过滤器在PubMed，EMBASE和Cochrane图书馆数据库中进行搜索。搜索包括进行和/或报告系统评价的所有建议。从每个建议中提取有关方法的数据。进行描述性分析。结果确定了83条建议。在过去的6年中，大约有60％的参考文献被发表。47％的研究提出了进行和报告系统评价的建议。每个建议中提出的有关进行和/或报告系统评价的指南各不相同。几乎96％的建议在系统评价方法部分提供了指导。仅29％的建议中提出了更新的需要和时间。40％的建议认可其方法适用于与医疗干预有关的任何主题。一半的研究未指定要纳入系统评价的研究设计。结论发表了一些进行和/或报告系统评价的建议，并提供了不同的指导。进一步研究这种异质性的影响可以提高系统评价的质量。一半的研究未指定要纳入系统评价的研究设计。结论发表了一些进行和/或报告系统评价的建议，并提供了不同的指导。进一步研究这种异质性的影响可以提高系统评价的质量。一半的研究未指定要纳入系统评价的研究设计。结论发表了一些进行和/或报告系统评价的建议，并提供了不同的指导。进一步研究这种异质性的影响可以提高系统评价的质量。
