Network analysis of depressive and anxiety symptoms in adolescents during the COVID-19 pandemic.
Article in Scientific reports, 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
Adolescence represents a critical period of vulnerability for the development of mental health disorders. The COVID-19 pandemic has exerted psychological impacts not only on adults but also on adolescents, largely due to various containment and transmission control measures. Identifying these psychological effects and exploring their interrelationships is essential for informing mental health services. The present study aimed to use network analysis to cross-sectionally identify the most central symptoms within the depressive-anxiety symptom network in a sample of adolescents during the pandemic. Depressive symptoms were assessed using The Patient Health Questionnaire-9 (PHQ-9), while anxiety symptoms were measured with The Generalized Anxiety Disorder-7 (GAD-7) scale. The network analysis revealed that PHQ-2 (sad mood), GAD-1 (nervousness), PHQ-4 (fatigue), and GAD-2 (uncontrollable worry) emerged as the most central symptoms in the network model. Additionally, the key bridge symptoms linking depressive and anxiety symptom clusters were PHQ-6 (feelings of guilt), PHQ-2 (depressed mood), and GAD-5 (restlessness). Identifying these central and bridge symptoms through network analysis may offer valuable insights for designing targeted interventions for adolescents. Furthermore, this study provides an important foundation for future research, representing the first investigation conducted within a Turkish adolescent sample.
