Negative emotional processing and decision-making inhibition deficits in adolescents with NSSI: a cross-sectional ERP study.
Article in Frontiers in psychology, 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
Background: This study utilises ERP technology and the Iowa Gambling Task (IGT) to compare the behavioral and EEG characteristics of adolescents with non-suicidal self-injury (NSSI) and those with depression in response to negative emotional stimuli, with the aim of exploring the specific neural mechanisms underlying negative emotion processing and inhibitory control in adolescents with NSSI. Methods: This study employed a cross-sectional between-groups design to compare 32 adolescents with NSSI and 34 adolescents with depression. All participants completed the emotion-face-based modified Iowa Gambling Task, whilst 64-channel EEG recordings were simultaneously acquired. The analysis focused on behavioral measures and ERP components such as the early posterior component and LPP. Results: The net IGT score in the NSSI group was significantly lower than that in the Depression group [ Conclusion: Adolescents with NSSI exhibit a 'differentiation between early and late stages' in the processing of negative emotions: in the early stage, there is insufficient differentiation in the encoding of negative emotions, whilst in the late stage, there is a marked attentional bias toward fearful faces; this provides electrophysiological evidence for NSSI.
