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: The primitive lateral basilovertebral anastomosis (PLBA) is a transient embryonic vessel in the vertebrobasilar system that typically regresses during cerebellar artery development. Persistent PLBA (PPLBA), which forms a vertebrobasilar duplication, is a rare vascular anomaly. This is the first reported case of multiple fusiform aneurysms associated with a PPLBA. Case Description: A 14-year-old girl was diagnosed with intracranial aneurysms before undergoing coronary artery bypass grafting surgery for myocardial infarction. Digital subtraction angiography showed two fusiform aneurysms on a PPLBA, connecting the left vertebral artery (VA) and the left anterior inferior cerebellar artery (AICA). After 3 years of follow-up, a new aneurysm developed at the origin of the PPLBA, proximal to the existing two aneurysms. Due to the AICA blood flow originating mainly from the basilar artery (BA) rather than the PPLBA, endovascular parent artery occlusion of the PPLBA was planned to prevent aneurysmal rupture and subarachnoid hemorrhage. Complete occlusion of all three aneurysms was achieved without complications. Conclusion: Understanding the embryological anatomy of this rare vertebrobasilar duplication involving the PPLBA, AICA, BA, and VA facilitated the successful development of a therapeutic strategy. Aneurysms associated with PPLBA exhibit various vascular structures and can be treated effectively with tailored endovascular approaches.
