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 Anhedonia (SA) is recognised as a negative symptom of the schizophrenia spectrum. Despite the emerging evidence of general impairment in Theory of Mind (ToM), the behavioural manifestation and underlying neural mechanisms of ToM deficits in SA remain unclear. The current study therefore adopted a multidimensional assessment approach to examine the effect of SA on ToM ability behaviourally and using fMRI. Methods: A total of 47 participants with high SA ( Results: The participants with low SA showed better performance for first-order ToM than for second-order ToM. However, those with high SA did not show such a differential effect. Based on the fMRI results, the low SA group showed more activation than the high SA group in the medial frontal cortex and posterior cingulate cortex in second-order ToM than in first-order ToM. Conclusion: The results demonstrate the impairment of ToM performance among those with high SA and highlight that it is crucial to examine the pattern of results rather than solely focusing on general ToM.
