Internal auditory canal duplication with facial and cochlear nerve dysfunction: A case report.
Article in SAGE open medical case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Internal auditory canal duplication is a rare anomaly of the temporal bone. The condition is diagnosed on performing High-Resolution Computed Tomography of the temporal bone and magnetic resonance imaging for sensorineural hearing loss. A bony septum divides the internal auditory canal into dual compartments. Duplication may be either unilateral or bilateral and vestibulocochlear nerve may be aplastic or hypoplastic. Rarely, patient may present with facial nerve palsy. A 26-year-old female presented with right grade IV lower motor neuron facial nerve palsy for 12 years and right-sided hearing loss for 9 years. Pure tone audiogram revealed 45 dB of moderate degree sensorineural hearing loss on the right ear. On High-Resolution Computed Tomography of the temporal bone, an incomplete bony septum was visualized in the right internal auditory canal, dividing it into two compartments. Internal auditory canal on the left side was normal. Other inner and middle ear structures were normal. On magnetic resonance imaging, both the vestibulocochlear and facial nerves were well visualized with normal calibers.
