A rare encounter in the nasopharynx: Extramedullary plasmacytoma.
Article in Radiology case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Extra-medullary plasmacytoma (EMP) is a rare tumor that most frequently occur in the head and neck region, with the paranasal sinuses, nasopharynx and tonsils being the most common sites. Diagnostic criteria for EMP include histological confirmation of a solitary plasma cell lesion, the presence of fewer than 5% plasma cells in the bone marrow, and the absence of end-organ damage commonly associated with multiple myeloma. CT scans and MRI features are nonspecific and can mimic those of other conditions. EMP of the nasopharynx presents as a slow-growing, radiosensitive mass with a favorable prognosis. We present the case of a 55-year-old male patient who sought medical attention for recurrent epistaxis. An endoscopic examination revealed a tumor located in the nasopharynx, which was confirmed by MRI as a confined nasopharyngeal mass. Subsequent pathology studies, laboratory results, and bone marrow biopsy were consistent with a solitary EMP of the nasopharynx.
