The use of dynamic magnetic resonance angiography in the diagnosis of rotational vertebral artery syndrome.
Article in Annals of the Child Neurology Society, 2024. 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
Background: Rotational vertebral artery (VA) syndrome represents a rare mechanical vasculopathy that can lead to vertebrobasilar insufficiency and ischemic stroke. Objective: We describe a 10-year-old boy with a history of chronic morning emesis who presented with acute onset dizziness, gait instability, and vomiting and was diagnosed with acute ischemic posterior circulation stroke. Interpretation: Contrast-enhanced magnetic resonance angiography (MRA) of the head and neck with dynamic positioning demonstrated loss of flow-related enhancement with head tilted to the left, conferring a diagnosis of rotational VA syndrome. He started aspirin monotherapy and subsequently underwent C1 laminectomy, with both radiographic and clinical improvement on follow-up. Conclusion: Dynamic contrasted-enhanced MRA imaging can serve as a noninvasive alternative to digital subtraction angiography in the diagnosis of rotational VA syndrome and should be considered in suspected cases of pediatric rotational arteriopathy.
