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

Periampullary carcinoma refers to a malignant tumor within 2 cm of the duodenal ampulla. Primary ampullary carcinoma is very rare, accounting for only 0.2% of malignant gastrointestinal tumors. The small intestine accounts for 75% of the length of the gastrointestinal tract, and primary tumors in the small intestine account for only 2% of all gastrointestinal tumors. Here, we report the case of a duodenal ampullary tumor with malignant transformation of parapapillary polyps. The patient had both a primary ampullary tumor and high-grade intraepithelial neoplasia of juxtapapillary adenomatous duodenal polyps.
