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

objectiveTo provide the clinico-radiologic and histopathologic illustration of a unique case of sinonasal intravascular papillary endothelial hyperplasia (IPEH; Masson's tumor). METHODOLOGY: Case report and review of literature.

resultsA 29-year-old man presented with right-sided nasal obstruction and occasional blood-tinged mucopurulence for two years. Diagnostic naso-endoscopy revealed a fleshy polypoid mass occupying the right nasal cavity encroaching into the nasopharynx. The mass was tender and firm, and bled on touch. Gadolinium-enhanced magnetic resonance imaging done two months prior showed a large, heterogenous mass in the right nasal cavity, partly involving the maxillary sinus, and extending into the nasopharynx. The findings were corroborated in a recent contrast-enhanced computed tomography scan that revealed mild contrast uptake and bone remodeling due to expansile nature of the mass without any erosion. An infected antrochoanal polyp, vascular tumor, and neoplastic lesions (including inverted papilloma) were considered as differentials. A subsequent punch biopsy revealed histologic pictures suggestive of IPEH. The mass was excised completely through endonasal endoscopic approach, and it was found to originate from the right inferior turbinate. The final histopathology confirmed the biopsy findings. Troublesome bleeding was encountered both during the biopsy and endoscopic excision of the mass. The patient is symptom-free with no recurrence at one-year follow-up.

conclusionsSinonasal IPEH (Masson's tumor) is an extremely rare entity; only 14 patients have been reported in the last four decades as evident from the PubMed/MEDLINE search. The present report adds to the existing literature, summarizes the clinico-radiologic and histopathologic perspectives, highlights the surgical challenges, and underlines the importance of having a low threshold of suspicion for considering this entity as a differential in a bleeding sinonasal mass.
