Mapping emotion-modulated inhibitory control in borderline personality features: a dimensional approach using the emotional Go/No-Go task with EEG.
Article in Borderline personality disorder and emotion dysregulation, 2025. 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
backgroundTo explore how emotional-modulated inhibitory control, as assessed by the emotional Go/No-Go task and EEG, correlates with the multidimensional profile of borderline personality disorder (BPD).
methodsEighty-two participants completed the Personality Assessment Inventory-Borderline Features (PAI-BOR), Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) scale. EEG was recorded during an emotional Go/No-Go task and event-related potential (ERP) components were analyzed for correlations with BPD features. Participants were then divided into groups with or without BPD features, and comparisons of ERP components were then made within groups.
resultsERP analysis revealed BPD features correlations with brain activity. Affective instability was positively correlated with left frontal N2 during positive-neutral No-Go trials. Self-harm was associated with left frontal late positive potential(LPP) during negative-neutral Go trials. Left frontal and central LPP slightly related to identity problems. 32 participants grouped into participants with BPD features(the BPF group) showed more depression, anxiety, emotional instability, identity issues, self-harm, and interpersonal problems. The BPF group had impaired performance on No-Go trials, smaller N2 amplitudes at left frontal channels during negative emotional cues, and delayed N2 peak latency. A group-trial type interaction was observed, with higher LPP amplitudes in Go trials for the control group but not in the BPF group, indicating distinct emotion processing between the BPF and control groups.
conclusionThe findings of this study propose that there are neural associations among affective instability, self-harm, and identity problems in BPD, which are consistent with the neural foundation of emotion-modulated inhibitory control observed in the emotional Go/No-Go task. The lack of association between negative sociality and ERP components highlights the complex nature of social information processing in BPD. Moreover, significant emotional, cognitive, and neural differences are also observed between the BPF and control groups. These results enhance understanding of how emotional valence modulates inhibitory control processes in individuals with varying levels of BPF.
