Fig. 2

Summary of measured outcomes. Each row represents an outcome of interest. Columns are divided by statistical significance, with the no difference column representing studies that found no statistically significant relationship for the outcome of interest. Individual studies are represented by circles and are colored green for low risk of bias, yellow for moderate risk of bias, and red for high risk of bias. The size of each circle is representative of the number of participants in the study, but not directly proportional. Each study can be represented by more than one circle if it investigated more than one outcome of interest
