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
backgroundThe clinical diagnosis and treatment of dilation of the cholangiopancreatic duct in patients with ambiguous ampullary disease, termed unexplained dilation of the cholangiopancreatic duct (UDCD), is commonly difficult. This study aimed to evaluate the applicability of transduodenal ampullectomy (TDA) for the diagnosis and treatment of UDCD.
methodsWe first proposed a surgical exploration procedure based on the TDA and applied it in a representative UDCD patient. We retrospectively analyzed the pathological diagnosis and prognosis of 14 patients at our hospital and 189 patients reported in existing studies who were treated with TDA between January 2010 and December 2022.
resultsTDA can be used to radically explore the ampullary region and harvest adequate pathological tissue, which is helpful for identifying the cause of UDCD. The diagnostic rate of intraoperative frozen pathology was greater than that of preoperative endoscopic biopsy (78.41% vs. 65.94%, P = 0.044). The postoperative complication rate was 27.07%, with a mortality rate of 0.00%. The 5-year survival rate was 68.31% in patients with adenocarcinoma, 85.99% in patients with adenoma with HGD/pTis, and 100% in patients with benign lesions, and these had a statistically significant difference (P = 0.021).
conclusionsTDA-based surgical exploration can be used as a safe and effective transitional procedure in the treatment of UDCD.
