Funnel Plot

A scatterplot of treatment effect against a measure of study size used primarily as a visual aid for detecting bias or systematic heterogeneity. A symmetric inverted funnel shape is seen in ‘well-behaved’ data for which publication bias is unlikely and which is thus suited for inclusion in a meta-analysis. An asymmetric funnel indicates a relationship between treatment effect and study size, due either to publication bias or a systematic difference between smaller and larger studies—‘small study effects’
