Association Between Frontotemporal Atrophy and Cognitive Impairment in Patients with Schizophrenia Based on Computed Tomography Imaging.
Article in Neuropsychiatric disease and treatment, 2026. 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
Background: Patients with schizophrenia (SZ) exhibit frontotemporal atrophy accompanied by cognitive impairment. However, the relationship between CT-derived structural changes and cognitive deficits remains underexplored. This study aimed to evaluate the association between frontotemporal atrophy and cognitive performance using routine cranial CT. Methods: This retrospective cross-sectional case-control study included 120 patients with SZ and 100 healthy controls. Bifrontal ratio (BFR), frontal horn width (FHW), mean temporal horn width (THW_mean), sylvian fissure width (SFW), and frontotemporal atrophy index (FTAI) were measured. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) and the Trail Making Test (TMT). Group comparisons, Spearman correlation, and multivariable regression analyses were performed. Results: Patients with SZ showed significantly increased atrophy indices and reduced cognitive performance. FTAI was negatively associated with global cognition, executive function, and attention. In multivariable models, FTAI remained significantly associated with cognitive outcomes and contributed to improved model fit (ΔR Conclusion: CT-derived frontotemporal atrophy was significantly associated with cognitive impairment in SZ. These findings suggest that CT-based structural measures may provide a clinically accessible approach for characterizing brain changes related to cognitive dysfunction.
