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

Although the Frey procedure effectively treats chronic pancreatitis, late relapse can occur in the pancreatic tail. This paper details the essential steps of combining the Frey procedure with distal pancreatectomy (Frey + DP) to address this issue. The key surgical steps include distal pancreatectomy, longitudinal opening of the main pancreatic duct, pancreatic head coring, and longitudinal pancreaticojejunostomy. Comparing the outcomes of nine Frey + DP and 13 Frey-alone patients (2016-2024), Frey + DP had significantly longer operative times and higher estimated blood loss. However, the postoperative hospital stay, mortality, 1-year pain recurrence, and new-onset diabetes were comparable between the two groups. Although more invasive, Frey + DP definitively treats concurrent severe tail disease, mitigating the risk of late relapse and requiring difficult reoperations. Frey + DP is a safe and effective approach for patients with chronic pancreatitis with inflammatory lesions in both the pancreatic head and tail.
