Impaired emotional response inhibition among adolescents with bipolar depression: evidence from event-related potentials and behavioral performance.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundImpaired inhibition of inappropriate responses in the emotional context is a core feature in patients with bipolar disorder. However, there has been little research exploring the underlying mechanism of impaired response inhibition for emotional stimuli in adolescents with bipolar depression. To explore this issue, we employed event-related potentials (ERPs) to investigate the underlying neuroelectrophysiological mechanisms of inhibition of inappropriate emotional stimuli in adolescents with bipolar depression.
methodsTwenty-five adolescents with bipolar depression and nineteen healthy controls completed an emotional Go/No-Go task during electroencephalography recording. Reaction time (RT), reaction time variability (RTV), discriminability, and response bias were measured as behavioral performance indicators. ERP components, theta-band oscillation and inter-trial coherence (ITC) were compared between the two groups.
resultsBehavioral performance analysis found that adolescents with bipolar depression showed smaller d' values, and larger RT and RTV, than healthy controls. Nogo-P3 amplitude was decreased in adolescents with bipolar depression in comparison with healthy controls. Theta-band oscillation and ITC for emotional stimuli were also reduced in adolescents with bipolar depression. Pearson correlation analysis showed there was a negative correlation between the Nogo-P3 amplitude induced by negative trials and RTV in adolescents with bipolar depression.
conclusionOur findings suggest that adolescents with bipolar depression exhibit abnormal response inhibition in the emotional context. Impaired attentional function and discrimination of emotional information are related to the failure of behavioral inhibition in negative emotional contexts, and attenuated P3 amplitude and theta-band oscillation could be an electrophysiological indicator for this impairment.
