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
backgroundThe escalating prevalence of mental health issues and sleep disturbances among Chinese adolescents has become a pressing public health concern. Despite increasing recognition of this issue, there remains a paucity of research elucidating the intricate interplay between anxiety symptoms and sleep patterns. To address this critical gap, this study employs advanced network analysis to explore the complex relationships between these two domains, offering novel insights into their interconnectedness.
methodsWe conducted a large-scale, online, cross-sectional survey encompassing 48,074 adolescents. Anxiety symptoms were assessed using the Generalised Anxiety Disorder Scale-7 (GAD-7), while sleep quality was evaluated via the Pittsburgh Sleep Quality Index (PSQI). Daytime sleepiness and fatigue symptoms were measured using the Chinese Adolescent Daytime Sleepiness Scale and the Fatigue Symptom Scale (FSS). Demographic data were analysed using chi-square tests, and continuous variables were examined via t-tests. To investigate symptom-level relationships, we employed network and mediation effect analysis, providing a robust methodological framework.
resultsOur findings reveal a concerning prevalence of anxiety and insomnia symptoms among adolescents, at rates of 32.1% and 39.9%, respectively. Adolescents exhibiting anxiety symptoms reported significantly higher levels of insomnia, fatigue, and daytime sleepiness. Mediation effect analysis uncovered a chain mediation pathway, whereby insomnia and fatigue symptoms sequentially mediated the relationship between anxiety and daytime sleepiness. Network analysis further identified GAD2 (uncontrollable worry) and PSQI7 (daytime function) as pivotal core symptoms, with FSS (fatigue symptoms) demonstrating the highest expected impact within the network.
conclusionsThis study underscores the persistent severity of anxiety and sleep pattern disturbances among adolescents. These findings highlight the importance of addressing core symptoms-particularly GAD2 and PSQI7-in therapeutic interventions. The results provide a solid foundation for developing more effective, symptom-specific strategies to improve adolescent mental health and sleep quality.
