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
A 63-year-old male presented with acute onset of intermittent dizziness, visual disturbances, and left temporal headache. Investigations revealed a dural arteriovenous fistula (dAVF) at the left sigmoid sinus, classified as Cognard type IIb. Successful therapeutic transvenous embolization was performed using coils and Onyx, resulting in complete resolution of the dAVF without immediate complications. However, 3 days post-embolization, the patient developed headache, dizziness, visual discomfort, and alexia. MRI findings suggested vasogenic oedema in the left temporo-occipital area due to venous outflow obstruction. Despite treatment with enoxaparin and dexamethasone, the patient experienced progressive symptoms including difficulty in object naming, memory decline, and nonconvulsive seizures. Follow-up imaging indicated improvement of oedema and stable minimal focal gliosis. This rare case of a patient developing alexia following endovascular embolization of a dural AVF highlights the importance of post-procedural monitoring and suggests potential benefits of prophylactic anticoagulation to reduce the risk of probable complications.
