Cannabis-induced ischemic stroke involving the basilar and middle cerebral arteries in a 50-year-old man: a rare case report.
Article in Oxford medical case reports, 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
Cannabis use has been increasingly associated with cerebrovascular events, though simultaneous large-vessel occlusions in both anterior and posterior circulations are rare. We report a case involving a 50-year-old male with no medical history who presented with decreased consciousness and left-sided hemiplegia. CT angiography imaging revealed acute occlusion of the right middle cerebral artery (MCA) and the basilar artery. Urine toxicology was positive for cannabis. Extensive cardiac and laboratory workups were unremarkable. The patient underwent successful mechanical thrombectomy, achieving full reperfusion (TICI 3) without complications. With no identifiable alternative cause and a history of chronic cannabis use, a diagnosis of cannabis-associated large-vessel ischemic stroke was made. To our knowledge, this is the first reported case of concurrent MCA and basilar artery occlusions in this context. This case highlights the need for increased awareness of cannabis as a potential risk factor for multi-territory ischemic stroke, particularly in patients without traditional vascular risk factors.
