Angiographically Silent Ruptured Dural Arteriovenous Fistula Presenting As Subdural Hematoma.
Article in Cureus, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Dural arteriovenous fistulas (dAVF) are aberrant vascular communications that can have devastating effects ranging from headaches to death. Typically, these malformations are identifiable on a CT angiogram (CTA) and confirmed via catheter angiography. We present a case of a female patient who presented with a headache and was found to have a large holohemispheric subdural hematoma. Given the lack of trauma, a CTA was performed. The CTA revealed abnormal vessels in the anterior temporal lobe spanning her hematoma. A diagnostic cerebral angiogram was performed; no early venous drainage was detected. When the patient was taken to the operating room for subdural hematoma evacuation, an aberrant connection from a superficial cortical vein to the middle meningeal artery was identified and ligated. Although rare, this case demonstrates that patients can present with ruptured vascular malformations that are radiographically silent on cerebral angiography.
