Substance use and the value of control.
Article in Cognitive, affective & behavioral neuroscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Clinical criteria for substance-use disorder collectively specify a loss of instrumental control over consumption; yet little empirical work has addressed how substance use shapes the utility of agency in motivated behavior. We combined a hierarchical gambling task with cross-sectional substance-use surveys and computational cognitive modeling to assess the preference for controllable environments in adult humans with self-reported abstinence from psychostimulants, opioids, alcohol, or sedatives. For psychostimulant use, longer abstinence selectively increased the preference for instrumental control. In contrast, for opioids and alcohol, longer abstinence respectively predicted increased preferences for divergent outcome distributions and free choice, regardless of controllability. These associations between substance use and decision making were dissociable from participants' ability to maximize monetary payoffs in controllable environments. Our findings implicate the dopaminergic system in agency coding.
