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 adenocarcinoma is a rare malignancy whose carbonic anhydrase IX (CA9) expression remains poorly understood. A 73-year-old man visited our hospital for a medical checkup. Transnasal endoscopy revealed a submucosal, tumor-like lesion with a central depression located in the descending part of the duodenum on white light imaging. On texture and color enhancement imaging mode 1, the lesion was highlighted as a reddish, elevated lesion with an irregular mucosa in its central depressed area. Pancreaticoduodenectomy was performed on the suspicion of duodenal adenocarcinoma for biopsy and endoscopic diagnosis, which led to the lesion being diagnosed as tubular adenocarcinoma, pT1b (SM). Immunohistological staining revealed an adenocarcinomatous component positive for CA9, as well as a normal duodenal mucosa. To our knowledge, this report is among the first to describe CA9-expressing primary duodenal adenocarcinoma.
