Enhancing meningioma resection: a comprehensive study on the safety and effectiveness of Onyx™ presurgical embolization.

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
Presurgical embolization (PE) has emerged as an interesting strategy to help turn brain tumor resection more amenable. This study aims to systematically review the safety and effectiveness of Onyx™ PE in meningioma resection. We followed Cochrane Collaboration and PRISMA for systematic review and meta-analysis, querying PUBMED, Cochrane Library, Web of Science, and Embase databases. Major complications were defined as other artery occlusion, visual deficits due to PE, or non temporary nerve damage, while minor included transitory conditions and others without clinical implications. A total of 186 patients were included, in which 120 were WHO grade I (80%), II (16%), and III (4%). Patient baseline characteristics and complications were distributed in groups without or with individual patient data analysis. Individual Patient Data Meta-Analysis (IPDMA) was performed on the last category, comprising 51 meningiomas that underwent Onyx™ PE. Among available data, 70%, 17%, and 13% were WHO grade I, II, and III, respectively. Considering all studies, tumor characteristics regarding grade underscored a certain homogeneity. Complications occurred at a rate of 9% (95% CI, 4 to 14%; I
