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
introductionCerebral arteriovenous malformations (CAVMs) are rare, with an estimated prevalence of 0.01%. Symptoms typically present in adults under 40, often beginning with hemorrhage in 61% of cases. The annual risk of hemorrhage is between 2-4%, with a mortality rate of 10%, and 50% of survivors may experience permanent neurological deficits. Embolization can induce changes in the angioarchitecture of the affected vessels. Our case uniquely demonstrates a morphological alteration in the carotid artery (CA) and its primary branches, associated with the presence of a CAVM. Detailed Case Presentation: A 52-year-old patient presented to the Emergency Department with weakness, shortness of breath, dizziness, nausea, and vomiting that began earlier that morning. Clinical and radiological evaluations suggested acute bleeding from a ruptured CAVM. The patient was admitted for digital subtraction angiography (DSA) and potential embolization. DSA confirmed the presence of a CAVM, supplied by the middle meningeal and occipital arteries, with distortion of the left CA angioarchitecture. Selective catheterization and embolization using Onyx 18 were successfully performed. After receiving supportive treatment, the patient was discharged in good condition. A follow-up CT scan three months later showed complete resolution of the brain pathologies. A repeat angiogram revealed no recanalization of the CAVM, with normalization of the CA and its branches. The patient is currently asymptomatic.
conclusionsDetection of pathological changes in the head and neck arteries linked to CAVM can predict rupture risk and complicate endovascular access. Identifying these changes early warrants consideration of interventions to prevent hemorrhage, though alternative access routes or strategies may be needed for safe, effective treatment.
