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

Malignant gastrointestinal neuroectodermal tumors (MGNETs) are extremely rare malignant mesenchymal tumors derived from ectodermal neural cells of the gastrointestinal tract that most commonly arise in the small intestine. Preoperative diagnosis is challenging owing to the lack of well-established imaging characteristics. Here, we report the case of a 50-year-old female patient with MGNET of the ileum. Computed tomography revealed a highly lobulated hypervascular mass and circumferential wall thickening in the distal ileum, whereas magnetic resonance imaging revealed marked diffusion restriction. A laparoscopic ileal resection was performed. The patient remained recurrence-free for 1 year without additional treatment. Specific imaging characteristics observed in our case, including the combined pattern of wall thickening and submucosal mass formation, marked diffusion restriction, and highly lobulated appearance, may aid in differentiating MGNET from other tumors.
