MRI Vessel Wall Imaging and Treatment of an Aneurysm at the Atlanto-Axial Segment of an Aberrant Vertebral Artery.
Article in Neurointervention, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
We report a case of unique location of an aneurysm at the atlanto-axial extradural segment of a unilateral aberrant vertebral artery. The MRI vessel wall imaging findings and possible mechanism of aneurysm formation were discussed. A 5 mm extracranial vertebral artery aneurysm located at the interlaminar space between C1 and C2 was diagnosed in a woman presenting with occipital headache. The index vertebral artery ran an aberrant course at the V3 segment, where it entered the dura between C1 and C2 instead of the usual atlanto-occipital space. MR vessel wall imaging showed homogenous wall enhancement of the aneurysm sac. We surmise the anomalous course of the vertebral artery subjected the V3 segment to repeated shearing force secondary to the atlanto-axial rotational neck movement. This led to vessel wall trauma and inflammation, and subsequent aneurysm formation. The aneurysm was successfully treated with endovascular coiling with resolution of symptoms.
