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
backgroundSocial cognitive impairment is a key vulnerability marker for psychosis and is commonly observed in individuals at clinical high risk (CHR). However, the neurophysiological mechanisms underlying abnormalities in emotional intensity processing remain unclear. This study investigated behavioral and electrophysiological responses to emotional intensity in CHR individuals using an event-related potential (ERP) paradigm.
methodsThirty CHR participants, 29 healthy controls (HCs), and an exploratory sample of 30 individuals with schizophrenia (SCZ) completed the Emotional Intensity Recognition Task (EIRT) during high-density EEG recording. Behavioral measures included reaction time (RT) and accuracy and were analyzed across six basic emotional categories. ERP components, including N100, N170, P200, P300, and LPP, were analyzed across predefined frontal, central, parietal, and occipital regions. ERP analyses also included neutral expressions because identifiable EEG event markers were available. Associations between ERP indices, behavioral performance, and clinical symptoms were also examined.
resultsCHR individuals showed significantly slower RTs than HCs across emotional conditions, while accuracy remained comparable. ERP analyses, including neutral expressions where EEG markers were available, revealed altered modulation of emotional face processing across multiple temporal stages. Group-related effects were most consistently observed for P300 amplitude and LPP latency, suggesting atypical attentional allocation and late evaluative processing in CHR individuals. Exploratory correlation analyses suggested associations between selected ERP indices and clinical symptoms; however, these findings were not corrected for multiple comparisons and should be interpreted cautiously. Exploratory unadjusted comparisons with the SCZ group suggested group differences in selected ERP measures, but these findings should be interpreted cautiously because the SCZ group was older and was not collected concurrently with the primary CHR and HC samples.
conclusionsIndividuals at clinical high risk for psychosis exhibit slowed behavioral responses and altered ERP modulation during emotional intensity processing. These findings suggest that the EIRT-ERP paradigm may help characterize social-cognitive and neurophysiological alterations in the psychosis prodrome. Larger longitudinal studies are needed to determine whether these ERP measures have predictive value for functional outcomes or transition to psychosis.
