Research reviews that systematically synthesise evidence (e.g. Systematic reviews, Meta-analysis, Scoping reviews, Mixed methods reviews, etc) should be submitted as Original research. Please include the research type in your title to make the nature of your study clear. Following the lead of The BMJ and its <a href="https://www.bmj.com/campaign/patient-partnership">patient partnership strategy</a>, <em>Gut</em> is encouraging active patient involvement in setting the research agenda. As such, we require authors of Research Articles to add a <a href="/pages/authors/#PPI">Patient and Public Involvement statement</a> in the Methods section. <strong>Visual Abstracts</strong> As of 1 September 2024, <em>Gut</em> requires a visual abstract to accompany original research submissions. This should be in the format of one PowerPoint slide and authors should follow the template and instructions provided <a href="/gut/wp-content/uploads/sites/16/2024/07/Gut-Visual-Abstracts-Instructions-and-Template.pptx">here.</a> The visual abstract is an opportunity for authors to present the key findings of their work in a pictorial manner to increase the visibility of their paper.
