The Long-Term Impact of Adolescent Community Weapon-Related Violence Exposure on Depression: Insomnia as a Mediating Pathway.
Article in Journal of community psychology, 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
Adolescents exposed to community weapon-related violence face increased mental health risks, including depression, with insomnia linked to negative mental health outcomes. Given the high rates of insomnia in this population, this study explores insomnia as a mediator between community weapon-related violence and adult depression. Using data from the National Longitudinal Study of Adolescent to Adult Health, we analyzed the association between adolescent weapon-related violence (Wave 1) and depression in adulthood (Wave 4), with insomnia (Wave 2) as a mediator (N = 3924). Community weapon-related violence was associated with higher levels of depression in adulthood, 13 years post-exposure, through insomnia (β = 0.01, p = 0.01). Insomnia accounted for 7% of the total effect of weapon-related violence on depressive symptoms, indicating a partial mediation effect. Our findings identify a pathway through which adolescent community weapon-related violence leads to depression in adulthood, underscoring the need for early interventions targeting insomnia to reduce long-term depression risk in this population.
