Anal squamous cell carcinoma with metastasis to duodenum causing duodenal stricture and gastric outlet obstruction.
Article in AME case reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
Squamous cell carcinoma (SCC) of the anal canal is a rare entity encompassing only 2-4 percent of all colon, rectal, and anal cancers. SCC of the anal canal tends to be loco-regional, and in the event of distant metastasis, a most common site of spread is to liver and lung. We report an unusual case of SCC of the anal canal with duodenal metastases in a 49-year-old female who had presented with symptoms of abdominal pain, nausea, and vomiting eight months after the primary diagnosis of SCC of the anal canal. Esophagogastroduodenoscopy (EGD) revealed duodenal stricture with subsequent biopsy revealing duodenal mucosa with scattered malignant cell clusters within lymphatic spaces, consistent with metastatic carcinoma. Immunohistological staining demonstrated malignant cells positive for CK7, p16, p63 favoring a metastatic SCC.
