The content of a research poster generally follows the logic of a research paper:
Introduction: thesis/problem presented in a clear and concise way
Methods: describe them in two or three sentences
Results: graphs, tables, and/or charts summarizing the findings
Discussion: clear arguments based on your findings
Conclusion: summary and “what’s next” usually placed on the bottom right side of the poster
References: smaller fonts could be used – do not distract from the main content
A literature review poster will also usually contain a table summarizing the articles/sources being reviewed.
This table will include references to the articles (in the format of in-text citations) and might include sample size, methods, interventions, outcomes, or other particulars depending on the subject.
