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: Hemosuccus pancreaticus (HP) is a rare cause of gastrointestinal bleeding, characterized by the pathological passage of blood from the pancreatic duct into the duodenum via the ampulla of Vater. HP presents considerable diagnostic and therapeutic challenges due to its nonspecific clinical presentation and the intermittent nature of bleeding. Case Description: A 62-year-old male with no history of pancreatitis, abdominal trauma, or surgery presented with recurrent abdominal pain and hematochezia over 3 months, acutely worsening in 72 hours. Initial evaluation revealed severe anemia (hemoglobin 5.4 g/dL) and a 2.2 cm × 2.0 cm saccular splenic artery pseudoaneurysm (SAP) without active extravasation on computed tomography (CT). Despite transfusion (hemoglobin transiently improved to 7.8 g/dL), the patient experienced recurrent hematochezia and subsequent hematemesis. Angiography confirmed the SAP but showed no active extravasation; endoscopy failed to identify the bleeding source. Upon transfer due to hemodynamic deterioration (hemoglobin 4.0 g/dL), emergency CT revealed a 2.8 cm × 2.3 cm proximal SAP with active contrast extravasation into the descending duodenum. This finding, together with endoscopic visualization of bleeding from the ampulla, strongly supported the diagnosis of HP secondary to the SAP. The patient underwent successful endovascular embolization using the "sandwich" technique with Amplatzer vascular plugs (AVPs) and microcoils. Conclusions: This case underscores the diagnostic difficulty of HP, especially when initial imaging shows no active bleeding. A high index of suspicion is warranted in patients with obscure recurrent gastrointestinal bleeding, particularly in the presence of a known SAP. Timely diagnosis relies on multimodal imaging, including contrast-enhanced CT, endoscopy, and angiography. Endovascular embolization offers a safe, minimally invasive, and effective therapeutic option.
