Systematic mapping assesses the nature of an evidence base, answering how much evidence exists on a particular topic. Perhaps the most useful outputs of a systematic map are an interactive database of studies and their meta-data, along with visualisations of this database. Despite the rapid increase in systematic mapping as an evidence synthesis method, there is currently a lack of Open Source software for producing interactive visualisations of systematic map databases. In April 2018, as attendees at and coordinators of the first ever Evidence Synthesis Hackathon in Stockholm, we decided to address this issue by developing an R-based tool called EviAtlas, an Open Access (i.e. free to use) and Open Source (i.e. software code is freely accessible and reproducible) tool for producing interactive, attractive tables and figures that summarise the evidence base. Here, we present our tool which includes the ability to generate vital visualisations for systematic maps and reviews as follows: a complete data table; a spatially explicit geographical information system (Evidence Atlas); Heat Maps that cross-tabulate two or more variables and display the number of studies belonging to multiple categories; and standard descriptive plots showing the nature of the evidence base, for example the number of studies published per year or number of studies per country. We believe that EviAtlas will provide a stimulus for the development of other exciting tools to facilitate evidence synthesis.

EviAtlas:可视化证据综合数据库的工具

系统映射会评估证据基础的性质,回答特定主题上存在多少证据。系统地图最有用的输出可能是研究及其元数据的交互式数据库,以及该数据库的可视化效果。尽管作为证据合成方法的系统地图的数量迅速增加,但是目前缺乏用于产生系统地图数据库的交互式可视化效果的开源软件。在2018年4月,作为斯德哥尔摩有史以来首次证据综合黑客马拉松的参与者和协调员,我们决定通过开发基于R的工具EviAtlas解决此问题,该工具称为EviAtlas,是一种开放访问(即免费使用)和开源(即软件)代码是可自由访问和可复制的)工具,用于产生交互式,引人注目的表格和数字总结了证据基础。在这里,我们介绍我们的工具,其中包括生成系统化地图和评论的重要可视化内容的功能,如下所示:完整的数据表;空间明确的地理信息系统(证据图集);交叉映射两个或多个变量并显示属于多个类别的研究数量的热图;以及显示证据基础性质的标准描述性图表,例如每年发表的研究数量或每个国家的研究数量。我们相信EviAtlas将为其他令人兴奋的工具的开发提供刺激,以促进证据综合。空间明确的地理信息系统(证据图集);交叉映射两个或多个变量并显示属于多个类别的研究数量的热图;以及显示证据基础性质的标准描述性图表,例如每年发表的研究数量或每个国家的研究数量。我们相信EviAtlas将为其他令人兴奋的工具的开发提供刺激,以促进证据综合。空间明确的地理信息系统(证据图集);交叉映射两个或多个变量并显示属于多个类别的研究数量的热图;以及显示证据基础性质的标准描述性图表,例如每年发表的研究数量或每个国家的研究数量。我们相信EviAtlas将为其他令人兴奋的工具的开发提供刺激,以促进证据综合。
