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
introductionIntracranial artery dissections are rare diseases, usually associated with subarachnoid hemorrhage. Rarer presentations are ischemic stroke and isolated headache. The V4 vertebral artery (VA) is one of the most frequent location for intracranial dissection.
methodsWe are presenting four cases of V4 VA dissections without hemorrhagic presentation from a single center from 2023 to 2025 Two of the presented patients had an ischemic stroke and two had isolated headache. All patients were admitted to the Emergency Department and underwent non contrast computed tomography (NCCT) and CT angiography (CTA) for diagnostic purposes. The diagnosis in V4 VA dissection was confirmed by Magnetic Resonance Imaging (MRI) and mural hematoma and/or intimal flap were identified using vessel wall imaging (VWI). DISCUSSION: Intracranial dissections and dissecting aneurysms can present with ischemic or hemorrhagic complications. Imaging, including CTA, MRA, and HR-VWI, is essential for diagnosis, identifying features like fusiform dilation, stenosis, intramural hematomas, and intimal flaps. Dissections can heal in various ways, but persistent aneurysmal changes may increase stroke risk. Prognosis varies, with ischemic cases prone to recurrence and hemorrhagic cases at higher risk for rebleeding. No standardized treatment exists, though antithrombotic therapy and intravenous thrombolysis are used based on limited data.
conclusionsIntracranial VA dissections without subarachnoid hemorrhage are rare diseases and without a dedicated multidisciplinary pathway of care might be missed or remain underdiagnosed, preventing the design of therapeutic studies.
