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

This article reports a novel case of a ruptured distal anterior cerebral artery (DACA) aneurysm. Initial laser-cut stent-assisted coiling resulted in significant recurrence at 1 month follow-up. Salvage treatment was then successfully performed with a flow diverter (FD) telescopically deployed within the original stent. One month follow-up angiography showed complete aneurysm obligation, classified as O'Kelly-Marotta (OKM) grade D, with unobstructed parent artery and branches. We also explored the possible mechanisms of recurrence and treatment strategies. To the best of our knowledge, this is the first reported case of successfully retreating a recurrent ruptured DACA aneurysm from a less than 2 mm parent artery using FD telescoping after failed stent-assisted coiling.
