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: In dural arteriovenous fistulas, bridging veins are connecting vessels that drain venous blood from the surface of the brain to the surrounding dural sinus. It is rare for the fistulous point and the bridging vein to be at different levels. Observations: A 71-year-old man presented with progressive spinal symptoms of 8 months' duration. Angiography showed that the jugular branch of the ascending pharyngeal artery was the feeding artery, with the fistulous point at the jugular foramen and the bridging vein at the foramen magnum level, draining into the spinal vein. Direct surgery was performed via a transcondylar fossa approach, allowing visualization of both the fistulous point and the bridging vein, and successful venous outflow occlusion was achieved. The surgery was completed without complications, and the patient's spinal symptoms gradually improved over time. Lessons: For jugular foramen dural arteriovenous fistulas with a bridging vein at the foramen magnum level, a direct surgical approach via the transcondylar fossa, which allows visualization of both the fistulous point and the bridging vein, was useful for achieving a safe and definitive occlusion. https://thejns.org/doi/10.3171/CASE25477.
