Evidence maps and evidence visualizations are systematic evidence synthesis products that visually display evidence gaps or study characteristics, and sometimes summarize study quality or synthesized evidence from multiple studies. The interactive visuals provide an overview of the state of the evidence and inform research priorities.
For the best interactive experience, we recommend viewing these evidence maps and evidence visualizations on desktop-sized devices in a Chrome, Safari, or Firefox browser.
