The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement has been developed as a guideline for reporting systematic reviews and meta-analyses. Despite the prevalent use of the PRISMA statement in medicine and nursing, no studies have examined authors' perception of it. The purpose of this study is to explore the perception of the PRISMA statement of authors who published reviews, meta-analyses, or both in nursing journals.
Cross-sectional descriptive study.
An online survey was conducted among authors who published reviews, meta-analyses, or both in nursing journals between 2011 and 2017. The selected authors' email addresses were extracted from the PUBMED database. A questionnaire-with a 10-point Likert scale (1- to 10-)-was developed to elicit their responses regarding their perception of not only the PRISMA statement as a whole, but also the individual items therein.
Invitations were sent to 1960 valid email addresses identified, with 230 responses (response rate: 11.7%) and 181 completed responses (completion rate: 9.2%). The average perceived importance of the PRISMA statement was 8.66 (SD=1.35), while the perceived importance for the individual items ranged from 7.74 to 9.32. Six items were rated significantly higher than the average rating, whereas one item was rated significantly lower.
Most respondents perceived the PRISMA statement as important. Items related to information sources, selection, search-flow presentation, summary of findings, limitations and interpretation were deemed more important while the registration was deemed less so.
《系统评价和荟萃分析的首选报告项目（PRISMA）声明》已被制定为报告系统评价和荟萃分析的指南。尽管 PRISMA 声明在医学和护理领域得到广泛应用，但尚无研究探讨作者对其的看法。本研究旨在探讨发表在护理期刊上的综述、荟萃分析或两者兼有的作者对 PRISMA 声明的看法。
横断面描述性研究。
对 2011 年至 2017 年期间在护理期刊上发表综述、荟萃分析或两者兼有的作者进行了在线调查。从 PUBMED 数据库中提取了所选作者的电子邮件地址。设计了一个包含 10 分制（1 分到 10 分）的问卷，以了解他们对 PRISMA 声明整体以及其中各个项目的看法。
向 1960 个有效电子邮件地址发出邀请，收到 230 份回复（回复率：11.7%）和 181 份完整回复（完成率：9.2%）。PRISMA 声明的平均感知重要性为 8.66（SD=1.35），而单个项目的感知重要性范围为 7.74 至 9.32。有 6 个项目的评分明显高于平均评分，而有 1 个项目的评分明显低于平均评分。
大多数受访者认为 PRISMA 声明很重要。与信息来源、选择、搜索流程呈现、研究结果总结、局限性和解释相关的项目被认为更为重要，而注册则被认为不那么重要。
