重视系统评价和Meta分析优先报告条目在眼科的应用

Attach importance to implication of ＂Preferred Reporting Items for Systematic Reviews and Meta-Analyses＂in ophthalmology

作为一种汇总既往的研究结果而获得更高级别证据的循证医学实践方法，系统评价和Meta分析受到越来越多研究者的重视，近年来一些专业的二次文献分析论文的数量明显增加，但与此同时，很多相关论文的质量却堪忧，如分析和撰写的报道条目不统一、内容不全面，甚至许多描述不详，限制了系统评价和Meta分析论文的循证作用，也影响对所汇总证据的判读和有效利用。系统评价和Meta分析优先报告条目（PRISMA）是针对系统评价和Meta分析的一种论文报告规范，但在我国眼科领域的认知程度并不高，我国眼科医师实施和发表的系统评价和Meta分析也较少遵循PRISMA的条目进行规范。学习和了解PRISMA不仅有益于提高论文质量，对于熟知高质量临床研究的关键要素也大有裨益，甚至能够帮助临床医生规范自己的医疗行为，对于更好地开展眼科领域的循证医学研究具有重要意义。

As a part of evidence-based medical practice to obtain high-level evidence through summarizing previous studies,systematic review and meta-analysis have been paid more and more attention. The number of papers published is increasing recently. However, many relevant published papers in biomedical sciences revealed low quality, such as non-uniform and incomprehensive items,and even unclear narrative in many portions of review. These problems reduced the evidence-based role of systematic review and Meta-analysis paper,and affected the interpretation and effective availability of summarized evidence. Preferred Reporting Items for Systematic Reviews and Meta-Analyses （PRISMA） is a report standard,but it has not been well-known in ophthalmology of China. The systematic review and meta-analysis published by Chinese ophthalmologists are less guided by PRISMA. Learning PRISMA is helpful not only for improving quality of papers, but also for acquainting the key elements of high-level clinical research, even for standardizing the medical code of conduct, which are important to make it better for conduct evidence-based research in ophthalmology.
