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

Dural arteriovenous fistulas (DAVFs) are rare but significant intracranial vascular malformations that are usually idiopathic and can lead to severe complications like venous hypertension and intracranial hemorrhage. We present 2 cases of DAVF occurring after venous sinus stenting (VSS) for presumed idiopathic intracranial hypertension (IIH) in a 51-year-old and a 52-year-old female. In both patients, Cognard type 1 DAVF was detected by Catheter angiography and successfully obliterated with Onyx™ embolization. These cases suggest that VSS may either unmask pre-existing DAVFs by altering intracranial pressure dynamics or induce new fistula formation by angiogenic factors or stent-induced hemodynamic changes. Clinicians should maintain an index of suspicion for DAVF in patients with persistent symptoms post-VSS and catheter angiography might be needed to detect the DAVFs.
