1 · What the graph read from it

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.

2 · The registry

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

This study presents the rare case of an intraosseous dural arteriovenous fistula (DAVF) draining into the diploic veins in the left frontal bone with high-flow feeder, successfully treated with transarterial Onyx embolization. A 59-year-old male exhibited mild right hemiparalysis and aphasia without prior head trauma, surgery, or venous sinus thrombosis. Imaging identified DAVF, fed by the bilateral superficial temporal arteries, left middle meningeal artery, and left occipital artery, draining retrogradely solely through the diploic veins into the superior sagittal sinus, causing cortical venous reflux (CVR). Treatment involved Onyx embolization under flow control, preventing Onyx (Medtronic, Irvine, CA, USA) migration and achieving complete DAVF occlusion, resolving the neurological deficits. This case highlights the clinical significance of diagnosing and managing DAVF draining exclusively into the diploic veins, emphasizing the effectiveness of Onyx embolization in such cases.
