"Double Trouble": Ultra-Early Formation and Rupture of a De Novo Terminal Basilar Artery Aneurysm After Aneurysmal Subarachnoid Hemorrhage.

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.
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
Introduction: The formation of de novo intracranial aneurysms (DNIAs) often occurs months or years after the initial identification of an intracranial aneurysm. Consensus on surveillance after surgery remains elusive. Case Presentation: A 53-year-old woman presented with a recurrent subarachnoid hemorrhage (SAH) caused by a rapidly expanding de novo basilar tip aneurysm, which developed and ruptured within 6 days of a previous SAH due to the rupture of a posterior communicating artery aneurysm. Both SAH incidents were successfully treated with microsurgical clipping. A computed tomography angiography at a 1-year follow-up did not detect any DNIAs. Conclusion: DNIAs can form within days after primary surgery. Therefore, conducting early postoperative angiography is crucial to detect and manage DNIAs and prevent SAH, especially in high-risk cases. In addition, since DNIAs are more prone to rupture, early clinical intervention is recommended.
