Bile duct MALT lymphoma diagnosed with direct cholangioscopy: a case report.
Article in Clinical journal of gastroenterology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) extremely rarely arise in extrahepatic biliary tract. Here, we report a case of bile duct MALT lymphoma diagnosed with direct cholangioscopy. The patient was an 80-year-old female with history of esophageal cancer, and had been occasionally treated with balloon dilatation for anastomotic stricture. She was referred to our hospital for treatment of choledocholithiasis. Since transesophageal endoscope insertion was impossible, stone extraction by transjejunal approach was performed. When gastroduodenoscope was directly inserted to the bile duct (direct cholangioscopy), accidentally two flat lesions with development of large atypical vessels in hilar region were noted. Biopsy revealed diffuse infiltration of CD20 positive small- to medium-sized atypical lymphocytes. A diagnosis of bile duct MALT lymphoma was made. The patient underwent eight courses of chemotherapy with rituximab alone, with no evident complications. Although biliary tract MALT lymphoma is rare, advances in cholangioscopy may promote encounter with such lesions. Accumulation of endoscopic figures of biliary tract MALT lymphoma is required.
