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

Gastric glomus tumors are rare and challenging to diagnose preoperatively owing to their resemblance to other submucosal lesions. We herein report the case of a 35-year-old man with a 15 mm gastric submucosal tumor. Endoscopic ultrasonography depicted the tumor as a hyperechoic mass, whereas contrast-enhanced harmonic endoscopic ultrasonography showed homogeneous enhancement and a prolonged contrast effect from the early to delayed phases. Endoscopic ultrasonography-guided fine-needle aspiration showed uniform round cells, and immunohistochemistry confirmed a gastric glomus tumor. This rare gastric glomus tumor was identified preoperatively, thus highlighting the potential of these modalities in diagnosing patients with submucosal gastric tumors.
