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: Pancreaticoduodenectomy is the primary treatment modality for pancreatic and periampullary malignancies. Postoperative collections in the surgical area are common complications, and the management of such collections often requires ultrasound-guided percutaneous drainage. However, when collections occur in challenging areas, conventional methods usually prove ineffective. Therefore, alternative approaches are needed. This study aims to evaluate the efficacy and safety of an improved ultrasound-guided percutaneous drainage technique for managing collections in challenging areas following pancreaticoduodenectomy. Methods: This retrospective study included 31 patients who underwent pancreaticoduodenectomy at the Qingchun Campus of The First Affiliated Hospital of Zhejiang University School of Medicine from January 2023 to September 2024 and developed fluid collections in challenging locations. All patients provided written informed consent before the procedure. Three different techniques were employed based on the location of the collections. Hydrodissection uses saline to separate tissues, creating a safe needle pathway. Modified trocar technique blunts the catheter tip by withdrawing the trocar stylet, reducing the risk of damage to adjacent organs. The transhepatic method involves passing a catheter through the liver to reach the target collection. After successful catheter placement, we evaluated and compared the technical and clinical success rates of the three methods and analyzed the associated complications. Results: A total of 31 patients with fluid collections in challenging areas were included in this study. Among these, the transhepatic method was the most frequently used technique (77.42%), followed by hydrodissection (12.90%) and the modified trocar technique (9.68%). Notably, all procedures achieved 100% technical success. The overall clinical success rate was 83.87% (26/31), with no statistically significant differences observed among the methods. No severe complications were reported in any of the cases. Conclusions: Ultrasound-guided drainage is a safe and effective procedure for managing fluid collections in challenging locations following pancreaticoduodenectomy.
