Support system networks: how support systems shape problematic social media use, mental health, and substance use in Czech adolescents.
Article in Child and adolescent psychiatry and mental health, 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
backgroundProblematic social media use (PSMU) has become a critical public health issue, with adolescents being one of the most engaged demographic. However, little is known about how distinct social support systems shape the associations between PSMU, mental health, and substance use.
objectiveThe first objective was to compare how support systems (peer, classmate, teacher, family, and self) shape the associations between PSMU, mental health, and substance use. The second objective was to explore which support systems are most prominent among boys and girls. METHODOLOGY: A representative sample of 5,487 Czech adolescents (50.88% boys, mean age = 15.48, SD = 0.53) was used for the analysis from the 2022 Health Behaviour in School-aged Children study. A network analysis based on undirected Mixed Graphical Models was used to examine the associations. Separate networks for each support system, stratified by gender, were estimated and compared.
resultsTeacher and classmate support altered the associations in boys, while peer support was more prominent for girls. Family support altered both networks, though its function varied between genders. Self-support functioned as a bridge symptom in both genders, connecting PSMU with mental health and well-being, particularly in girls. In boys, classmate and family support made the association between PSMU and heated tobacco use as well as irritability absent, whereas in girls, peer and family support shaped the links between PSMU and well-being.
conclusionThe findings highlight the gender-specific nature of support systems and underscore the need for more nuanced approaches when facilitating external and internal support in adolescents.
