A Meta-Analysis of the Effects of Transcranial Direct Current Stimulation on Anger and Aggression.
Synthesis in Aggressive behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Anger and aggression are causes of significant suffering. Psychological methods to prevent and reduce anger and aggression have been partially successful; however, there is room for novel interventions, such as those informed by neuroscience. One such intervention is anodal transcranial direct current stimulation (tDCS), which involves administering a weak electrical current to the brain to stimulate cortical activity. In this meta-analysis, we synthesized 93 effect sizes from 25 sham-controlled experiments. We predicted that tDCS would reduce anger and aggression. The overall results showed no effect of tDCS on anger and aggression (Hedges' g = -0.03, CI
