Spongiotic osteoma in the external auditory canal: Two cases of a rare tumor.
Article in SAGE open medical case reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Osteoma of the external auditory canal is a rare benign tumor with an estimated incidence of 0.05% of total otologic surgeries. In most cases, an osteoma in the external auditory canal does not cause symptoms because the tumor grows slowly and does not occlude the ear canal. However, if the mass grows to occlude the external auditory canal, several symptoms can occur, including conductive hearing loss, aural fullness, and keratin debris accumulation. We present two cases of this rare tumor in a 23-year-old woman and a 19-year-old man. The mass was surgically excised at the level of the peduncle under local anesthesia with microscope assistance. The base of the excised mass was drilled with a diamond burr to remove all osseous lesions. Histopathologic findings showed spongiotic osteomas. In these cases, patients had symptoms of aural fullness, although the osteomas did not completely occlude the external auditory canal, and the symptoms improved after surgical excision without recurrence.
