This figure shows the effect size (standardized mean difference ‘SMD’) with 95% confidence interval for each study in a forest plot for pharmacological and food supplement interventions for the outcome of subjective loudness. Three studies show a SMD with 95% confidence interval that crosses 0 (no difference) between groups, while three studies show a SMD with 95% less than 0 (Favors treatment group as compared to control group).
