PRISMA声明旨在提高系统综述和META分析报告的完整性，该声明已经广泛用于指导系统综述和META分析的报告和发表。原始的PRISMA声明是针对两种干预措施比较的传统的系统综述与META分析而制定的，然而，随着多种干预措施比较的系统综述的发展，实施和报告这一类系统综述面临较大挑战。此时，针对网状META分析的PRISMA扩展声明应运而生，旨在提高网状META分析系统综述的报告质量。PRISMA扩展声明是由专家们通过DELPHI调查、面对面讨论和共识大会而最终确立的。PRISMA扩展声明是在原始PRISMA声明的报告清单的基础上经过修改，最终确定了32个条目，每个条目均与网状META分析报告的内容直接相关。本文对网状META分析的PRISMA扩展声明进行了阐述，对报告清单各条目进行了举例说明，并详细说明了在原始PRISMA声明的基础上新增和修改各条目的理由。此外，PRISMA扩展声明强调了在网状META分析的实际操作中需要重点关注的信息。本文的目标读者包括网状META分析的作者与读者，以及期刊杂志的编辑与同行评审。“,”The PRISMA statement is a reporting guideline designed to improve the completeness of reporting of systematic reviews and meta-analyses. Authors have used this guideline worldwide to prepare their reviews for publication. In the past, these reports typically compared 2 treatment alternatives. With the evolution of systematic reviews that compare multiple treatments, some of them only indirectly, authors face novel challenges for conducting and reporting their reviews. This extension of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) statement was developed specifically to improve the reporting of systematic reviews incorporating network meta-analyses. A group of experts participated in a systematic review, Delphi survey, and face-to-face discussion and consensus meeting to establish new checklist items for this extension statement. Current PRISMA items were also clarified. A modified, 32-item PRISMA extension checklist was developed to address what the group considered to be immediately relevant to the reporting of network meta-analyses. This document presents the extension and provides examples of good reporting, as well as elaborations regarding the rationale for new checklist items and the modification of previously existing items from the PRISMA statement. It also highlights educational information related to key considerations in the practice of network meta-analysis. The target audience includes authors and readers of network meta-analyses, as well as journal editors and peer reviewers.
