1 · What the graph read from it

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.

2 · The registry

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

Osteosarcoma rarely arises from the temporal bone, and few primary cases have been reported in adults. The prognosis of head and neck osteosarcoma is generally poor because of the complex anatomy in the region. Complete resection with negative margins is essential to adequately treat head and neck osteosarcoma. Preoperative imaging is crucial given the importance of complete surgical resection to prognosis. In this case, preoperative imaging, including computed tomography and magnetic resonance imaging, revealed a lobulated mass with coarse internal calcification, displacing the parotid gland and extending into the parapharyngeal space. The lesion lacked abnormal findings in the adjacent temporal bone on imaging, but a sarcomatous mass with central calcification could be the basis for including osteosarcoma in the differential diagnosis. We report this case of primary osteosarcoma originating from the temporal bone that was initially discovered as a parotid tumor.
