Substance use to cope with trauma: the interactive effect of insomnia and neighborhood socioeconomic status.
Article in Sleep advances : a journal of the Sleep Research Society, 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
Study Objectives: Emerging literature suggests insomnia predicts post-trauma substance use. Socioeconomic context may exacerbate this relation, such that individuals with insomnia living in more disadvantaged areas may face elevated risk of substance use after trauma. The present study is the first to test whether insomnia predicts later substance use to cope after trauma, and whether this effect is stronger for individuals from more disadvantaged areas. Materials and Methods: Patients recruited from an urban Level I trauma center following traumatic injury ( Results: The interaction between T1 insomnia and SES significantly predicted the frequency of substance use to cope one-month post-trauma ( Conclusions: Living in less disadvantaged areas exacerbated the prospective effect of insomnia on risk for substance use to cope after trauma. Trauma patients with insomnia may benefit from sleep-focused interventions that consider alternative coping strategies to substance use.
