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
Introduction: Fear-themed digital media exposure is increasingly common in school-aged children, yet its developmental implications remain insufficiently understood. Rather than conceptualizing frightening content as inherently pathogenic, emotionally intense media may act as a mild arousal stimulus within a neurodevelopmental system characterized by heightened limbic reactivity and still-maturing regulatory control. The present study examined whether fear-themed exposure is associated with dimensional variability in sleep regulatory sensitivity, consistent with a tentative developmental PhenoSleep construct. Methods: This cross-sectional study included 132 children aged 5-11 years (mean age = 8.69 years, SD = 2.01), divided into an exposed group ( Results: Compared to controls, exposed children showed higher CBCL Total Problems and SDSC Total Scores. Domain-specific differences were modest and not uniformly distributed across subscales. Within the exposed group, engagement intensity showed small positive associations with selected social, cognitive, and sleep-related measures, consistent with dimensional variability rather than overt dysfunction. Conclusion: The findings do not support a deterministic psychopathological effect of fear-themed digital exposure. Instead, they are compatible with the interpretation that emotionally salient media may function as a mild environmental probe revealing interindividual differences in sleep regulatory sensitivity. We tentatively introduce the PhenoSleep construct to describe developmental variability in sleep continuity and arousal modulation in response to emotionally intense stimuli. Longitudinal and physiologically informed studies are required to further examine and refine this developmental regulatory model.
