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

Pancreatic portal vein fistula (PPVF) is a rare condition, often a complication of chronic pancreatitis, involving communication between a pancreatic collection and the portal vein. Early diagnosis is crucial to prevent severe complications, including portal vein thrombosis and hemorrhage. This case report presents a 62-year-old man with HIV and congestive heart failure who developed a PPVF following walled-off necrosis due to acute pancreatitis. Diagnosis of this complication resulted from abdominal pain secondary to splenic artery branch bleeding into the collection, which was treated by embolization. Despite systemic complications, the patient recovered without the need for walled off necrosis drainage. This case underscores the challenge and the importance of individualized treatment for PPVFs and its complications.
