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

purposeSubarachnoid hemorrhage (SAH) due to a ruptured intracranial aneurysm is a neurologic emergency with diagnostic and management challenges. While traditional imaging techniques such as CT angiography and digital subtraction angiography remain essential, they may be inconclusive at identifying the culprit aneurysm when multiple aneurysms are present. METHODS/

resultsWe present a patient with SAH and four intracranial aneurysms identified on initial CT angiogram. MR vessel wall imaging (VW-MRI) played a pivotal role: it revealed focal wall enhancement in the basilar tip aneurysm, guiding successful targeted balloon assisted coiling.

conclusionThis case illustrates the value of VW-MRI in identifying ruptured aneurysms by assessing wall abnormality rather than just lumen morphology. VW-MRI employs high-resolution, black-blood MR techniques to visualize vessel wall pathology. Our findings support integrating VWI into acute management algorithms when conventional imaging is inconclusive, potentially improving diagnostic accuracy and outcomes in patients with complex aneurysmal SAH presentations.
