Association Between the Degree of Arterial Contact Angle and Survival in Patients With Borderline Resectable Pancreatic Cancer.

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
Aim: This study aimed to evaluate the impact of arterial contact angle on survival outcomes in patients with borderline resectable pancreatic cancer (BRPC) undergoing neoadjuvant treatment (NAT) and surgical resection. Methods: A retrospective analysis of 84 patients with BRPC with arterial contact who underwent NAT followed by surgery at the Shizuoka Cancer Center (2012-2021) was conducted. They were classified into two groups according to the arterial contact angle measured using preoperative computed tomography: < 90° ( Results: The larger-angle group had a significantly higher R1 resection rate (28% vs. 3%, Conclusion: An arterial contact angle of ≥ 90° was associated with higher R1 resection rates, increased recurrence, and poor survival in patients with BRPC. More aggressive multimodal treatment strategies, including extended NAT, may be necessary to improve the outcomes in these high-risk patients.
