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

Sinonasal teratocarcinosarcoma (SNTCS) is a rare, aggressive malignancy with epithelial, mesenchymal, and neuroectodermal components. We report the case of a 66-year-old man with right nasal obstruction and epistaxis. Imaging revealed a mass in the right nasal cavity and ethmoid sinus. Histopathology revealed immature squamous nests with clear cytoplasm, and immunohistochemistry confirmed multiphenotypic differentiation. Therefore, SNTCS was diagnosed. Owing to inoperability, the patient underwent chemoradiotherapy, which resulted in stable disease at 6 months. This case highlights the diagnostic complexity of SNTCS and suggests that nonsurgical management may be effective in select cases.
