Bubble Plots
Bubble plots are scatterplots that display the results of a meta-regression, which measures the association between the adjustments in treatment intervention and resulting effect sizes found in studies. 
Breaking down the bubble plot
The "bubbles" represent individual studies that are positioned in the plot according to their respective level of treatment intervention being tested and corresponding treatment effect size. The size of the bubbles is proportional to the respective study's inverse variance of the treatment effect sizes. The line passing through the bubbles represents the line of best fit for the results included in the plot.
