What's the harm? Examining police contact and amygdala reactivity among black adolescents.
Article in Social cognitive and affective neuroscience, 2025. 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
A growing literature links various experiences of adversity to brain activity, particularly in regions that support threat processing and the stress response (e.g. the amygdala). However, this work has not considered racialized adversities and the extent to which specific experiences (e.g. police contact) may be uniquely salient for marginalized communities (e.g. Black adolescents). In a sample of 131 Black adolescents, we found that a history of police contact was associated with heightened amygdala reactivity when viewing neutral faces. Activity was specific to the Basolateral (BL) subregion, a region involved in hypervigilance. Police contact uniquely contributed to amygdala activation over and above cumulative measures of threat and social deprivation experiences traditionally studied in adversity literature. This study highlights police contact as a form of racialized adversity that is important to consider when elucidating the neurobiological embedding of adversity, particularly among marginalized youth.
