Hemodynamic findings associated with intraoperative appearances of intracranial aneurysms.
Article in Neurosurgical review, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 1 of them a synthesis that pooled it.
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
Intracranial aneurysms can be classified into thick-walled aneurysms and thin-walled aneurysms according to their intraoperative appearances; previous publications have revealed that different kinds of intraoperative appearances were associated with intraoperative rupture and postoperative complications. Here, we tried to evaluate the association between hemodynamic features and aneurysm wall appearance using computational fluid dynamics (CFD) method. Forty-one consecutive patients with unruptured middle cerebral artery (MCA) bifurcation aneurysms were included in our study. Based on the appearances observed under the microscope, aneurysms were classified into two different types: thick-walled and thin-walled aneurysms. Preoperative computed tomographic angiography (CTA) was used for geometry reconstruction and CFD analysis. Morphological and hemodynamic parameters were compared between the two groups. Eighteen aneurysms were classified as thick-walled atherosclerotic ones according to their intraoperative appearances. Compared with thin-walled aneurysms, aneurysms with atherosclerotic changes had larger geometry parameters (aneurysm depth, maximum height, diameter, aspect ratio, size ratio), lower wall shear stress (WSS), and larger low WSS area ratio (LSAR). Thick-walled aneurysms characterized by atherosclerotic changes are associated with low WSS and larger LSAR. CFD may be a useful tool for discriminating the intraoperative appearance of cerebral aneurysms.
