Trauma and suicidality in adolescents with substance use disorders.
Article in Child and adolescent psychiatry and mental health, 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
backgroundSubstance use and traumatic experiences have been identified as risk factors for suicidal ideation and behavior in community samples. The aim of this study was to explore these associations in a clinical sample of adolescents with substance use disorder (SUD).
methodsThe sample included N = 342 adolescents aged 12 to 19 years from a specialized SUD outpatient unit. They reported on their substance use, trauma history, symptoms of posttraumatic stress disorder (PTSD) and depression, and life satisfaction either in a structured clinical interview or standardized questionnaires; they also completed a task assessing inhibitory control. These variables were compared for adolescents with and without suicidal ideation or behavior. Classification and Regression Trees (CART) models were developed to describe subgroups of participants.
findingsOverall, 34.2% of adolescent SUD outpatients reported suicidal ideation in the last two weeks and 26.0% fulfilled the criteria for suicidal behavior disorder in the last two years according to DSM-5. Female gender (OR = 2.88 and OR = 4.30) and sexual abuse (OR = 4.55 and OR = 5.33) were associated with higher odds of both suicidal ideation and behavior, respectively. Adolescents with suicidal ideation or behavior had significantly more severe SUD-related problems (d = -0.46 and d = -0.36), symptoms of PTSD (d = -1.38 and d = -1.04) and of depression (d= -1.77 and d = - 0.89) and lower life satisfaction (d = 0.98 and d = 0.81). The CART models identified symptoms of depression and PTSD as the variables that best distinguished participant subgroups.
conclusionsThese results indicate high rates of suicidal ideation and behavior in adolescents with SUD and underline the importance of assessing trauma when identifying and preventing suicidality in this population.
