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: Social cognition (SC) has emerged as a relevant neurocognitive domain in people with Multiple Sclerosis (pwMS), given its impact on everyday functioning. However, the neural mechanisms supporting SC performance in pwMS remain underexplored, highlighting the need for ecologically valid assessment paradigms capable of capturing both behavioral and neural aspects of social-cognitive functioning. In this study, we addressed this gap by investigating the clinical application of an fMRI-adapted version of the Edinburgh Social Cognition Test (ESCoT) to explore the neural correlates of SC functioning in pwMS. Methods: In total, 59 subjects (27 pwMS, mean EDSS = 3.74, and 32 healthy controls) were enrolled in this study and underwent a comprehensive neuropsychological assessment, including SC tests, and the fMRI-adapted version of the ESCoT. Results: No significant between-group differences were observed during the fMRI task performance. Across groups, the paradigm elicited activation within a network involving the bilateral middle temporal poles, left dorsomedial prefrontal cortex, and precuneus, regions consistently implicated in social-cognitive processing. Within the pwMS group, a significant association was identified between neural activation and behavioral SC performance (rho = -0.447, Conclusion: The findings support the applicability of the ESCoT as an ecologically valid neuropsychological paradigm for capturing the neural processes underlying SC abilities in a clinical population. The observed relationship suggests that increased activation of an executive neural hub may support SC proficiency in pwMS, potentially reflecting an early compensatory strategy.
