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

Paranasal sinus mucoceles are benign, encapsulated, cystic lesions lined by respiratory epithelium. These lesions arise from the obstruction of a sinus drainage ostium. Mucoceles represent one-tenth of sinus surgical pathology in adults. Sphenoid sinus mucocele constitutes less than 3% of all mucocele cases. A 28-year-old man with a history of chronic rhinosinusitis presented with a lesion causing expansion and erosion of the sphenoid sinus and clivus, which initially raised suspicion of a chordoma. The intraoperative study was consistent with a mucocele. The lesion was resected, and the patient's evolution was satisfactory. Sphenoid mucoceles are potentially dangerous lesions due to their ability to compress critical adjacent structures. Extension into the clivus, as observed in this case, is a rare presentation that can mimic neoplastic lesions such as chordomas.
