Unmasking Cerebral Venous Sinus Thrombosis Induced by Vitamin B12 Deficiency.
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
This is the case of a healthy, 45-year-old right-handed man with no past medical issues who presented with mild drowsiness, language difficulty, right-sided weakness, and headache. Vital signs were unremarkable, and on examination, he was drowsy and found to have expressive aphasia and right upper and lower extremity flaccid paralysis. The patient was found to have cerebral venous thrombosis on imaging, as a result of his vitamin B12 deficiency from a vegan diet. The purpose of this clinical reasoning case is to instruct readers on the localization of symptoms, key imaging findings, approach to the diagnosis and etiologic considerations, and the relevance of biochemistry to the pathophysiology of this case.
