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

We report a 21-year-old man who developed abdominal pain, bleeding, and anemia caused by a rare Epstein-Barr virus-related T/NK-cell lymphoproliferative disorder in the small intestine. Initial endoscopy detected ulcers in the duodenum and jejunum, but the cause was unclear from the clinical and imaging findings alone. Biopsy later showed abnormal lymphoid cell growth, and further testing, including immunohistochemistry and EBER staining, confirmed EBV-associated disease limited to the gastrointestinal tract. The patient began combination chemotherapy and remains under follow-up. This case highlights that such EBV-positive lymphoid disorders can be easily overlooked because their symptoms and endoscopic features are nonspecific. Careful tissue evaluation and timely treatment are crucial due to their aggressive behavior and uncertain prognosis.
