Fig 3. Caterpillar plot of all outcome measures included in the meta-analysis.

Efficacy measured as standardized mean difference between medication and placebo for the primary outcome (aggregate measure of mental-health-related symptoms). Standardized mean differences less than 0 favor medication, and those greater than 0 favor placebo. Horizontal lines indicate 95% confidence intervals for each included outcome measure; the horizontal points of the diamond are the limits of the 95% confidence interval of the overall summary measure.
