Carotid stump syndrome in radiation-induced bilateral carotid occlusive vasculopathy.
Article in Neuroradiology, 2026. 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
purposeTo document the occurrence of radiation-induced vasculopathy as a delayed complication in the treatment of head and neck cancers.
methodsWe present the case history and review the imaging findings in a 51-year-old man with a history of nasopharyngeal cancer, treated with radiotherapy 10 years prior to admission, who presented with a stroke syndrome. The pathophysiology, clinical and imaging features, and development of collateral pathways due to radiation-induced vasculopathy are discussed.
resultsThe patient had occlusion of the right and left common carotid arteries, as well as of the left internal carotid artery and the right subclavian artery. The proximally occluded vessels ended in tapered "stumps". CT angiography with Maximum Intensity Projection (MIP) and 3D Volume Rendering Technique (VRT) displayed the collateralisation of the occluded arteries via the thyrocervical trunks and ascending cervical arteries.
conclusionRadiation therapy for head and neck cancer is associated with a significantly increased incidence of radiation-induced vasculopathy and cerebrovascular ischaemic events. Carotid stump syndrome should be considered as a rare but serious cause of recurrent stroke and stroke-like symptoms.
