We present 4 types of graphic used in meta-analysis. The commonest is the forest plot, and we discuss important aspects of the basic form of this plot. We present 2 enhanced versions, one displaying the results of subgroup analysis, and the second displaying absolute risks alongside relative risks from a meta-analysis of a binary outcome. The funnel plot is a well-established graph for assessing publication bias. We show some alternative forms, including a recently suggested enhancement using contours. The third type is a bubble plot used to summarize the results of meta-regression. Finally, we show a graphic designed for network meta-analysis, presenting rankings of the treatments that are compared. We prepared programs and graphs using GenStat™, R, RevMan™, SAS™ and Stata™, and these are available from the website.
