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
objectivesNon-suicidal self-injury (NSSI) often coexists with depressive and anxiety symptoms in adolescents, jointly impairing their mental health. However, the interplay between NSSI and symptoms of depression, anxiety, and sleep problems remain unclear. This study aims to explore the association patterns among insomnia, anxiety, depression, and NSSI behaviors in adolescents.
methodsA total of 4 319 students from three secondary schools in southern Hunan Province were assessed using the Insomnia Severity Index (ISI), Generalized Anxiety Disorder-7 items (GAD), Patient Health Questionaire-9 items (PHQ), and the Adolescent Self-Injury Scale (ASIS) to evaluate insomnia symptoms, depressive symptoms, and NSSI behaviors, respectively. Network analysis was then conducted to examine the interrelationships among these symptom domains.
resultsNetwork analysis indicated that suicidal ideation within depressive symptoms was closely associated with NSSI (edge weight=0.15). Among the symptoms, ISI6 (sleep problems noticed by others, an insomnia symptom), GAD2 (difficulty controlling worries, an anxiety symptom), and PHQ2 (low mood, a depressive symptom) exhibited high strength centrality in the disease network (strength values: 0.88, 0.80, and 0.76, respectively). Additionally, anxiety symptoms including GAD5 (restlessness), GAD6 (irritability), GAD7 (feeling afraid), and depressive symptoms including PHQ2 (low mood), PHQ3 (sleep problems), and PHQ8 (psychomotor retardation/agitation) were identified as bridge symptoms in the network structure (bridge strength values=0.95, 1.32, 1.23, 1.21, 1.32, and 1.27, respectively).
conclusionsRestlessness, irritability, feeling afraid, feeling down, sleep problems, and psychomotor agitation/retardation may serve as key target symptoms for effective interventions addressing insomnia, anxiety, depression, and NSSI among adolescents.
