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

Primary duodenal cancer is very rare, accounting for approximately 0.3% of all gastrointestinal cancers. Duodenal cancer is most often located in the descending portion of the duodenum, and cancer of the bulb is exceedingly rare. Additionally, most types of duodenal cancers are histologically differentiated adenocarcinomas, and signet ring cell carcinoma of the duodenum is extremely rare. Since most cases of signet ring cell carcinoma of the duodenum are discovered at an advanced stage, endoscopic treatment is seldom indicated. Here, we report a case of a 72-year-old woman in whom endoscopic treatment was performed for early signet ring cell carcinoma of the duodenum localized in the duodenal bulb, with achievement of curative resection. This is a valuable report of endoscopic curative resection of signet ring cell carcinoma of the duodenal bulb.
