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
Background and Aims: Bleeding bile duct varices are rare vascular communications between the portal venous system and the biliary tree. They may arise from portal vein thrombosis, malignancy, or endoscopic injury and often present with life-threatening hemobilia. We describe a case of choledochal varices bleeding in a patient with hepatocellular carcinoma (HCC) successfully managed with endoscopic ultrasound-guided coil embolization and glue injection. Methods: A 62-year-old man with hepatitis C virus cirrhosis and portal vein tumor thrombus presented with hematochezia and right upper quadrant pain. He underwent prior stereotactic body radiation and was not a transplant candidate. Initial laboratory tests showed hemoglobin of 12 g/dL. CT angiogram revealed portal venous collateralization; esophagogastroduodenoscopy and colonoscopy were unrevealing. After a postcolonoscopy episode of brisk hematochezia and hemodynamic instability, small-bowel enteroscopy showed active bleeding from the ampulla. Results: Endoscopic retrograde cholangiopancreatography revealed hemobilia from the bile duct, and a covered metal stent was placed. EUS identified a large portal-system varix encasing the bile duct, which was successfully obliterated using coil and glue embolization. Conclusions: Biliovenous fistulas are a rare but serious cause of hemobilia in HCC. EUS-guided embolization offers effective, definitive therapy after initial stabilization with biliary stenting. Timely diagnosis and intervention are critical.
