Baseline demographic and aneurysm morphologic features associated with woven endobridge angiographic outcomes: A systematic review and meta-analysis.

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
backgroundThe Woven EndoBridge (WEB) device is an effective treatment for wide-neck aneurysms (WNA). This study aims to identify and compare anatomical and procedural factors that predicts the aneurysm occlusion, both adequate and inadequate after WEB device treatment.
methodsA systematic review and meta-analysis were conducted using PubMed, Embase, Scopus, and Web of Science, including studies up to October 25, 2024. Data on angiographic outcomes of WEB occlusion were extracted and analyzed using R version 4.4.2.
resultsNine studies (790 patients) were included. Female patients were 1.64 times more likely to achieve adequate occlusion than males (OR: 1.64, 95% CI: [1.06, 2.52], P = 0.026). Regular-shaped aneurysms had a 2.44-fold higher likelihood of adequate occlusion compared to irregular ones (OR: 0.41, 95% CI: [0.23, 0.74], P = 0.003). Aneurysm neck size was significantly smaller in the adequate occlusion group (3.9 mm vs. 4.4 mm, MD: -0.48 mm, 95% CzI: [-0.78, -0.18], P = 0.002). Maximum aneurysm diameter was also smaller in the adequate occlusion group (5.7 mm vs. 6.8 mm, MD: -1.13 mm, 95% CI: [-1.69, -0.57], P < 0.001). Aneurysm height was also significantly lower than the inadequate occlusion group (5.4 mm vs. 6.3 mm, MD: -0.92 mm, 95% CI: [-1.55, -0.29], P = 0.004).
conclusionSmaller aneurysm dimensions, regular shape, and female sex were associated with higher adequate occlusion rates after WEB treatment. These findings may guide patient selection strategies for optimizing aneurysm occlusion. Further high-quality studies are needed to confirm these associations.
