Primary Extraskeletal Osteosarcoma Arising from the Optic Nerve: A Rare Case Report.
Article in Ocular oncology and pathology, 2018. 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
Orbital location of extraskeletal osteosarcoma is extremely rare with only 4 cases reported so far in the English literature. We present the case of a 32-year-old female who presented with proptosis and complete loss of vision of the left eye. Contrast-enhanced computed tomography scan showed a densely calcified lobulated lesion in the left optic nerve showing strong enhancement. A left fronto-occipito-zygomatic osteotomy was conducted and a greyish brown tumor was identified. Histopathological and immunohistochemical examination of the curetted material revealed it to be extraskeletal osteosarcoma. A left partial maxillectomy with ethmoidectomy and left orbital exenteration was done and the patient was advised chemotherapy with radiotherapy.
