Forest plots are a way of graphically displaying the results of a meta‐analysis. They allow the reader to easily see the results of the individual studies in the meta‐analysis, and how much they are in agreement with one another, alongside the overall result of the meta‐analysis. They can also be used to show subgroup analyses within a meta‐analysis and summarize the results of a group of studies where no meta‐analysis is performed. In addition, they can be used to show subgroup analyses in an individual randomized trial. They have been produced in their current form since the 1980s. It is now possible to draw them in a variety of statistical software packages.
