Occult ascending pharyngeal artery pseudoaneurysm masked by CTA artifact after penetrating facial trauma: a case report.
Article in Journal of surgical case reports, 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
Penetrating facial trauma can result in vascular abnormalities that are difficult to identify on initial imaging due to artifact from retained fragments. External carotid artery pseudoaneurysms are uncommon but may carry significant morbidity if not promptly recognized. A 34-year-old female presented after a gunshot wound to the left face. Initial computed tomography angiography (CTA) demonstrated left vertebral artery V3 dissection, severe left internal carotid artery stenosis, and a comminuted mandibular fracture with retained ballistic fragments causing substantial streak artifact. Due to persistent concern for vascular injury, craniocervical angiography was performed and revealed distal left vertebral artery occlusion, left internal carotid artery dissection, and a pseudoaneurysm arising from the ascending pharyngeal branch of the external carotid artery. Coil embolization was successfully performed. Occult vascular injury should remain a concern following penetrating facial trauma despite nondiagnostic CTA findings. Early angiographic evaluation may influence management and operative planning.
