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

The PulseRider is a neuroendovascular adjunct for wide-necked intracranial aneurysms. The decreased metal burden of the PulseRider theoretically reduces artifact on radiologic imaging. However, we report here on a case of a patient who underwent PulseRider-assisted stent-coiling of a basilar tip aneurysm. He returned 19 months later for intermittent diplopia and darkening of vision but was neurologically intact on exam. Both contrast-enhanced and time-of-flight magnetic resonance angiography (MRA) demonstrated absence of signal in the basilar artery in the proximal anchors of the PulseRider. Given his lack of reproducible symptoms and high functional status, it is presumed that the imaging reflected artifact and not thrombosis/stenosis. Although the PulseRider is a useful treatment option for wide-necked intracranial aneurysms, the clinician should be aware that even contrast-enhanced MRA can produce artifact that resembles thrombosis/stenosis. Non-angiogram radiologic imaging modalities may be appropriate for evaluation for residual aneurysm but not patency of the parent artery.
