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

Background: Foreign body granuloma of the pituitary gland is an exceptionally rare inflammatory lesion that may mimic recurrent adenoma on neuroimaging. Case Description: We report the case of a 44-year-old woman who previously underwent endonasal endoscopic surgery for a nonfunctioning pituitary adenoma and later developed a sellar mass secondary to a foreign body granulomatous reaction. Magnetic resonance imaging suggested tumor recurrence; however, gadolinium-enhanced imaging was not performed because of the patient's known gadolinium allergy. Histopathological examination revealed xanthogranulomatous inflammation and a multinucleated giant-cell reaction to the suture material, without evidence of neoplastic recurrence. Conclusion: This case highlights the diagnostic challenges associated with postoperative sellar lesions and emphasizes the importance of histopathological confirmation in distinguishing foreign body granulomas from recurrent pituitary adenomas.
