Sex differences in imaging features including cerebral amyloid angiopathy markers in intracerebral hemorrhage.
Article in Frontiers in stroke, 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: Reports on sex differences in radiological characteristics of intracerebral hemorrhage (ICH) are few. Sex-related differences in hematoma location, volume, and imaging markers may contribute to variations in clinical presentation and outcome. We aimed to assess sex differences in non-contrast computed tomography (NCCT) features in an unselected ICH cohort. Methods: This observational study included 1,398 patients with spontaneous supratentorial ICH from the Skåne Hospital Region, Sweden (2016-2021), registered in Riksstroke. Radiological characteristics were compared between males and females. Multivariable logistic regression, adjusted for confounders, analyzed sex differences overall and stratified by hematoma location (deep/lobar). CAA probability was assessed using the simplified Edinburgh CT criteria. Results: Among 785 males and 613 females, hematoma volume, location, and antithrombotic use were similar. Women were older (79 vs. 73 years; Conclusion: In this large, unselected cohort of supratentorial ICH, no sex differences were observed in hematoma volume, location, or intraventricular extension. However, in lobar ICH, female sex was independently associated with subarachnoid extension and CT features suggestive of higher CAA probability. These findings indicate similar hemorrhage severity between sexes but differences in lobar hemorrhage morphology that require further validation and explanation.
