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
Background: Overt aggression may be associated with childhood maltreatment (CM), insomnia, and alexithymia, but the underlying mechanisms of these associations have not been fully explored in adolescents with major depressive disorder (MDD). Therefore, the present study aimed to deeply analyze the relationships between overt aggression and CM, insomnia, and alexithymia in adolescents with MDD, to reveal the mediating mechanisms, and to provide a theoretical basis for clinical interventions. Methods: From December 2024 to December 2025, this study included 251 adolescents with MDD. The Modified Overt Aggression Scale (MOAS), the 17-item Hamilton Depression Rating Scale (HAMD-17), the Childhood Trauma Questionnaire (CTQ), the Insomnia Severity Index Scale (ISI), and the Toronto Alexithymia Scale (TAS-20) were used to assess the adolescents' overt aggression, depression, CM, insomnia, and alexithymia. Additionally, we employed the PROCESS macro program to examine the mediating role of insomnia and alexithymia between CM and overt aggression. Results: The prevalence of overt aggression in adolescents with MDD was 66.1%. The regression analyses showed that age (Beta = -0.761, t = -2.967, Conclusion: The risk of overt aggression is significantly higher in depressed adolescents and is significantly associated with CM, insomnia, and alexithymia. Additionally, insomnia and alexithymia may play a mediating role between CM and overt aggression. Given these findings, comprehensive interventions for depressed adolescents with adverse childhood experiences, insomnia, and alexithymia, should be emphasized in clinical practice to effectively reduce their risk of overt aggression.
