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
Previous meta-analyses have shown that psychotic experiences are a potential clinical risk marker for self-injurious thoughts and behaviors. However, it is unclear whether hallucinations and delusions have different effects on self-injurious thoughts and behavior. The study was to provide an updated meta-analysis of the associations between different types of psychotic experiences and self-injurious thoughts and behaviors in children and adolescents. Fifteen cross-sectional and twenty-one longitudinal studies were included after searching for articles published before January 2025 according to PRISMA guidelines. This study was registered with PROSPERO (CRD42024523854). Random-effect models were used to obtain estimates of effect sizes and study quality was rated. Results showed that children and adolescents with psychotic experiences were more likely to engage in self-injurious thoughts and behaviors, with a 3.00-fold (95% CI: 2.15-4.20) and a 2.18-fold (95% CI: 1.92-2.46) increase in cross-sectional and longitudinal studies. After adjusting for co-occurring psychopathology, psychotic experiences still remained to be significant in cross-sectional (OR = 2.52, 95% CI: 1.94-3.28) and longitudinal studies (OR = 1.60, 95% CI: 1.30-1.97). Hallucinations (OR = 2.07, 95% CI: 1.90-2.25) were significantly more strongly associated with an increased risk of self-injurious thoughts and behavior compared to delusions (OR = 1.70, 95% CI: 1.51-1.92) in longitudinal studies. These findings highlighted the importance of assessing hallucinations as part of suicide prevention strategies in children and adolescents.
