Susceptibility vessel sign in patients with subacute ischemic stroke.

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: Limited information exists regarding susceptibility vessel sign (SVS) found beyond 24 hours after stroke onset. This study aimed to compare the presence and quantitative measurements of SVS between the large artery arteriosclerosis (LAA) subtype and the cardioembolism (CE) subtype in patients with subacute stroke. Methods: We retrospectively analyzed stroke survivors with the LAA subtype or the CE subtype who had occlusion or severe stenosis of the responsible intracranial large vessel and who had undergone susceptibility-weighted imaging (SWI) between day 3 and day 14 after stroke onset at Peking University First Hospital from December 2017 to January 2022. Independent reviewers evaluated the presence, location, length, and diameter of SVS. Multivariable logistic regression analysis was used to analyze the relationship between the presence of SVS and stroke subtype. Results: Among 173 stroke survivors, including 133 with the LAA subtype and 40 with the CE subtype, SVS was found in 95 patients. The presence of SVS was higher in the LAA group than in the CE group (59.4% Conclusions: In patients with subacute ischemic stroke caused by intracranial large vessel occlusion (LVO) or severe stenosis, the LAA group had a higher incidence and a longer SVS than did the CE group. This suggests that SVS may have potential value in the etiology diagnosis of patients with subacute stroke.
