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

backgroundMycotic aneurysms (MAs) typically present with intracranial hemorrhage but are a rare cause of subdural hematoma (SDH). Although infective endocarditis is the most common etiology, MAs may also result from bacteremia associated with intravenous drug use, meningitis, or poor dentition. Patients with ventriculoatrial shunts (VASs) are at increased risk for shunt-related bacteremia compared to those with ventriculoperitoneal shunts, potentially predisposing them to MA formation. OBSERVATIONS: This is the case of a 61-year-old female with a fusiform distal left middle cerebral artery MA presenting as an acute-on-chronic SDH without endocarditis, but with positive blood cultures and CSF cultures for Cutibacterium acnes from a long-term VAS. LESSONS: MAs can rarely present as SDHs and should be considered in the differential diagnosis for patients with a long-standing VAS due to the risk of subacute bloodstream infections. https//thejns.org/doi/10.3171/CASE25625.
