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

Peripheral aneurysms in the posterior circulation are rare vascular pathologies and their treatment remains challenging. Microsurgical procedures for these aneurysms are complex, lengthy, and highly invasive. Endovascular parent artery occlusion could be considered as an alternative treatment of choice; however, it is inherently challenging due to the small vessel caliber and fine manipulation required. Small bore flow-guided microcatheters (1.5 Fr) with high peripheral accessibility are currently available, whereas compatible coils remain limited. The brand-new i-ED coils can be compatible with these microcatheters. We herein present our patient series of peripheral aneurysms in the posterior fossa that were treated endovascularly, and discuss key technical tips and potential pitfalls.
