From: Benefits of the microalgae Spirulina and Schizochytrium in fish nutrition: a meta-analysis
Baujat bubble plot used to identify potential outliers in the Spirulina 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. Five trials in the upper right corner accounted for a large share of the observed heterogeneity and were also overly influential which merited further scrutiny.
