【讨论】Meta分析投稿到Plos One后要求补充的内容

投了一篇meta分析到Plos One，回信有一项如下，不太明白，请懂行的赐教：We note that this manuscript is a systematic review or meta-analysis; our author guidelines therefore require that you use PRISMA guidance to help improve reporting quality of this type of study. Please upload copies of the completed PRISMA checklist as supporting information and a flowchart as Figure 1.Information about the PRISMA guidance, and blank flowcharts and checklists, can be found here: http://www.prisma-statement.org/. Please note that if your study analyses clinical trials, we cannot proceed with consideration of your article until we have this information. If your meta-analysis or systematic review looks at studies other than clinical trials, then we request that you complete all parts of the PRISMA flow chart and checklist that are applicable. If you feel that this requirement should not apply to your study, please briefly explain the reason for this.
