Figure 2. Studies of dopamine transporter availability. The forest plot shows the effects sizes estimated using a random effects model and 95% confidence intervals of the difference between amphetamine/methamphetamine users and controls. There was an overall decrease in the dopamine transporter availability in methamphetamine users relative to controls (−0.91 [95% CI, −1.5 - −0.32], p <0.01).
