Publications of living systematic reviews (LSRs) are increasing rapidly. Guidance facilitating transparent, complete, and accurate reporting of LSRs is needed. This paper reports the development of an extension of the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 statement for LSRs (PRISMA-LSR). The PRISMA-LSR extension includes the PRISMA-LSR checklist, the PRISMA-LSR flow diagram, reporting recommendations for the LSR status, and an explanation and elaboration document. This extension has been developed as an “add-on” to the PRISMA 2020 statement, meaning it should be used in addition to the PRISMA 2020 statement. The PRISMA-LSR extension is expected to benefit authors, editors, peer reviewers, and users of LSRs through transparent, complete, and accurate reporting of LSRs. Living systematic reviews (LSRs) are attracting attention from researchers and medical journals.12 Between 2014 (when the LSR approach first emerged3) and 2019, the rate of publication of these systematic reviews was low; however, since 2019, there has been a rapid increase. Indeed, the total number of LSRs published in 2020 and 2021 exceeded the total number published before 2020.4 LSRs are characterised by a continual search of the literature so that new evidence can be incorporated soon after it becomes available.35 These reviews are particularly important when research is published rapidly and where concomitant policy decisions are required, such as during the covid-19 pandemic.678 The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 statement is intended to facilitate transparent, complete, and accurate reporting of systematic reviews.9101112 The PRISMA 2020 statement was designed primarily to provide guidance for systematic reviews of studies that evaluate the effects of interventions. While the statement was intended for original, updated, or living systematic reviews, the developers noted that there might be additional reporting considerations that …

PRISMA 2020 实时系统评价声明 （PRISMA-LSR） 的扩展：清单和解释


实时系统评价 （LSR） 的出版物正在迅速增加。需要促进透明、完整和准确报告 LSR 的指导。本文报告了 LSR 系统评价和荟萃分析首选报告项目 （PRISMA） 2020 声明 （PRISMA-LSR） 的扩展。PRISMA-LSR 扩展包括 PRISMA-LSR 检查表、PRISMA-LSR 流程图、LSR 状态报告建议以及解释和详细说明文件。此扩展已作为 PRISMA 2020 声明的“附加组件”开发，这意味着它应该与 PRISMA 2020 声明一起使用。PRISMA-LSR 扩展有望通过透明、完整和准确的 LSR 报告使作者、编辑、同行评审员和 LSR 用户受益。实时系统评价 （LSR） 正在吸引研究人员和医学期刊的关注。12 从 2014 年（LSR 方法首次出现时3）到 2019 年，这些系统评价的发表率很低;然而，自 2019 年以来，这一数字迅速增加。事实上，2020 年和 2021 年发表的 LSR 总数超过了 2020 年之前发表的总数。4 LSR 的特点是不断检索文献，以便在获得新证据后不久就可以纳入新证据。35 当研究快速发表并且需要伴随政策决策时，这些综述尤为重要， 例如在 covid-19 大流行期间.678 2020 年系统评价和荟萃分析的首选报告项目 （PRISMA） 声明旨在促进系统评价的透明、完整和准确报告。9101112 PRISMA 2020 声明的主要目的是为评估干预措施效果的研究的系统评价提供指导。虽然该声明旨在用于原始、更新或实时系统综述，但开发人员指出，可能还有其他报告注意事项......
