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
purposeEvaluating intracranial aneurysm (IA) rupture risk is essential for guiding management. Although intrasaccular thrombosis (IST) is less common, it can contribute to aneurysm growth, mass effect, and rupture. Aneurysm wall enhancement (AWE) on high-resolution MRI (HR-MRI) offers valuable insight into IST and IA progression. Using radiomics, we extracted spatial information of the aneurysm wall to characterize AWE. This study aimed to explore correlations between radiomics-based AWE profiles and gross hemodynamic parameters, integrating imaging and flow dynamics to better understand IST.
methodsRadiomic analysis was conducted on a cohort of 3T HR-MRI scans from IA with IST. Three-dimensional vascular reconstructions and CFD simulations were conducted to quantify hemodynamic parameters. Spearman's correlation was performed to correlate aneurysm morphology, AWE patterns, and aneurysmal hemodynamic characteristics.
resultsA total of 37 thrombosed IAs were included in the analysis, comprising 22 fusiform (59.5%) and 15 saccular (40.5%) aneurysms. Six AWE RFs demonstrated strong correlations with aneurysm volume and surface area (ρ > 0.7 for both). Ten AWE RFs were highly correlated with flow vortex parameters (ρ > 0.7), and one showed a strong correlation with wall shear stress (WSS)-related metrics (ρ > 0.7). In the subset of saccular IAs, 20 AWE RFs were strongly associated with WSS-related metrics. In contrast, fusiform IAs showed stronger correlations between AWE RFs and vortex core characteristics. These findings suggest that elevated AWE is closely associated with regions of high oscillatory shear index and unstable flow vortices, indicating a potential link between wall enhancement and disturbed intra-aneurysmal hemodynamics. Conclusions Stagnant flow may promote degenerative remodeling of the aneurysm wall and IST. A combined spatiotemporal analysis of hemodynamic parameters and AWE patterns provide information about underlying biological processes of IAs, including the development of IST.
