Exploring the inter-factor network of psychological abuse, life-event stress, and suicidal behavior: evidence from Chinese college students.

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: Suicide remains a leading cause of death among young adults, yet traditional mediation models often oversimplify the complex and interactive processes linking childhood psychological abuse, stress, and suicidal behavior. Objective: This study applied a network analytical framework to examine the inter-factor associations among dimensions of childhood psychological abuse, life-event stress responses, and suicidal behavior in Chinese college students. Methods: A total of 693 first-year college students completed validated self-report measures of childhood psychological abuse, stress responses to negative life experiences, and suicidal behavior. Gaussian graphical models were estimated using EBICglasso, and bridge centrality indices were computed to identify key nodes linking abuse, stress, and suicidality. Network comparison tests were conducted to examine gender differences in network structure and global connectivity. Results: The estimated network showed dense within- and cross-domain connections among psychological abuse, stress responses, and suicidal behavior. Neglect, intrusion, and arousal emerged as prominent bridge nodes linking early psychological abuse and suicidal outcomes through stress-related pathways. Network structure was invariant across genders; however, males exhibited significantly higher global network strength than females ( Conclusion: These findings suggest that suicide risk emerges from dynamic interactions among interrelated psychological systems rather than from linear causal pathways. By identifying bridge nodes-particularly arousal and intrusive stress responses-this study highlights potential leverage points for targeted, trauma-informed, and culturally sensitive suicide prevention efforts among college students.
