Posterior circulation hypoperfusion plays an important role in refractory otalgia: case report.
Article in BMC surgery, 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
This case explored the association among posterior circulation hypoperfusion, cryptogenic vertebral artery dissection (CVAD), and idiopathic intractable otalgia. A 67-year-old male patient, afflicted with recurrent right otalgia for over 50 years and misdiagnosed with otitis and trigeminal neuralgia, demonstrated posterior circulation hypoperfusion on cerebral CT perfusion imaging. Conventional vascular tests turned up nothing, yet dynamic contrast-enhanced CT (DCE-CT) disclosed a long-segment CVAD with endothelial flaps within the intracranial vertebral artery, precisely matching the hypoperfused territory. Post endovascular stent repair of the CVAD, the hypoperfusion normalized and the otalgia vanished. At 29 months, the patient remained pain - free without analgesics.This case highlights that CVAD-related posterior circulation hypoperfusion is a critical contributor to cryptogenic intractable otalgia. The evidence supports the efficacy of endovascular therapy as a promising intervention.
