FIGURE 1.

Standardized mean differences and 95% confidence intervals (CIs) stratified by type of drug. The point indicates the effect size for each study. The horizontal line through each box gives the 95% CI. The diamonds give CIs for each type of drug. d-Amph = dextroamphetamine; ER = extended release; ES = effect size; GXR = guanfacine extended-release; IR = immediate release; LA = long-acting; LCI = lower 95% confidence interval; LDX = lisdexamfetamine dimesylate; MAS = mixed amphetamine salts; MPH = methylphenidate; MR = modified release; No. = number of observations; OROS = osmotic release oral system; UCI = upper 95% confidence interval; XR = extended release.
