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
backgroundNon-suicidal self-injury (NSSI) is common among adolescents with depressive disorders and poses a major public health challenge. Rumination, a key cognitive feature of depression, includes different subtypes that may relate to NSSI through distinct psychological mechanisms. However, how these subtypes interact with specific NSSI behaviors remains unclear.
aimTo examine associations between rumination subtypes and specific NSSI behaviors in adolescents.
methodsWe conducted a cross-sectional study with 305 hospitalized adolescents diagnosed with depressive disorders. The subjects ranged from 12-18 years in age. Rumination subtypes were assessed using the Ruminative Response Scale, and 12 NSSI behaviors were evaluated using a validated questionnaire. Network analysis was applied to explore symptom-level associations and identify central symptoms.
resultsThe network analysis revealed close connections between rumination subtypes and NSSI behaviors. Brooding was linked to behaviors such as hitting objects and burning. Scratching emerged as the most influential NSSI symptom. Symptom-focused rumination served as a key bridge connecting rumination and NSSI.
conclusionSymptom-focused rumination and scratching were identified as potential intervention targets. These findings highlight the psychological significance of specific cognitive-behavioral links in adolescent depression and suggest directions for tailored prevention and treatment. However, the cross-sectional, single-site design limits causal inference and generalizability. Future longitudinal and multi-center studies are needed to confirm causal pathways and verify the generalizability of the findings to broader adolescent populations.
