Impact of aneurysm sac size on the effectiveness of endovascular coiling in patient-specific middle cerebral artery aneurysms: a computational study.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This study investigates the hemodynamic efficiency of endovascular coiling in the treatment of patient-specific middle cerebral artery (MCA) aneurysms using computational models of both original and scaled-down geometries. Computational fluid dynamic (CFD) is used for the blood flow modelling inside cerebral aneurysms. The Casson non-Newtonian model is employed to simulate blood flow dynamics, while a porous condition represents the coiling within the aneurysm sac. Key hemodynamic factors, including wall shear stress (WSS) and oscillatory shear index (OSI), are analyzed to evaluate the effectiveness of coiling across different aneurysm sizes. Results indicate that coiling significantly reduces rupture risk, with larger sac volumes demonstrating a more pronounced decrease in high-risk hemodynamic zones. These findings offer insights into optimizing endovascular treatments for varying aneurysm morphologies.
