Group comparisons of FA averaged across the entire prefrontal cortex-habenula tract in the heroin addiction group compared with healthy controls (A) and cocaine addiction groups (B). *p < .05, **p < .01, ***p < .001. FA = fractional anisotropy; HUD = heroin-addicted individuals CTL = control individuals; CUD+ = currently using cocaine-addicted individuals; CUD− = short-term abstinent cocaine-addicted individuals. Boxplots represent the median (center line), interquartile range (box), and 1.5x the interquartile range (whiskers).
