Acute Subdural Hematoma Without Subarachnoid Hemorrhage Due to Traumatic Aneurysm of the Posterior Cerebral Artery.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Acute subdural hematoma (ASDH) typically results from high-energy head trauma, such as motor vehicle accidents or severe falls. It can also be caused by minor head injuries in elderly individuals due to damage to bridging veins or small arteries, but it is considerably rarer in younger patients. A previously healthy 39-year-old man presented with progressive headaches and consciousness disturbance. The emergent computed tomography (CT) revealed ASDH covering most of the left cerebral hemisphere without subarachnoid hemorrhage (SAH). CT angiography (CTA) showed an irregularly shaped aneurysm at a distal branch of the left posterior cerebral artery (PCA) (quadrigeminal segment (P3 segment)/cortical segment (P4 segment)), suggesting that ASDH was caused by aneurysmal bleeding of the PCA. Digital subtraction angiography performed after a left decompressive craniectomy showed the aneurysm observed on CTA was suspected to be a pseudo-aneurysm, and parent artery occlusion was performed. This report presents a rare case of ASDH in a young individual without a history of head trauma. Our case highlights the importance of considering aneurysm rupture as a potential etiology in patients with ASDH without SAH, particularly in the absence of a history of head trauma.
