From: Benefits of the microalgae Spirulina and Schizochytrium in fish nutrition: a meta-analysis

Baujat bubble plot used to identify potential outliers in the Schizochytrium data set, showing the contribution of each study to the overall heterogeneity and its influence under a random effects model. The size of each point is proportional to its relative weight in the meta-analysis. One trial in the upper left corner was overly influential which merited further scrutiny.
