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

Background: Endovascular treatment for true anterior inferior cerebellar artery (AICA) aneurysm is challenging for preserving the AICA trunk. Ischemic tolerance of the sacrifice of AICA is controversial. We report a rare case of ruptured distal AICA aneurysm treated by intra-aneurysmal embolization preserving the AICA trunk. Case Description: A 77-year-old woman presented with a sudden headache and computed tomography showed a subarachnoid hemorrhage predominant in the left cerebellopontine angle. Cerebral angiography revealed a saccular aneurysm in the anterior pontine segment of the left AICA. Coil embolization underwent preserving the parent artery. There is no recanalization of the aneurysm at 26 months postoperatively. In this case, hemodynamic stress was suggested to be involved in the development of the aneurysm. Conclusion: For the patients in the old or at high risk of ischemia, intra-aneurysmal embolization should be tried as the first-line treatment.
