Outcomes of extended versus standard lymphadenectomy in pancreatoduodenectomy for pancreatic cancer: systematic review and meta-analysis.
Synthesis in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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: Pancreatic cancer has a poor prognosis, and surgical resection is the only curative option. Extended lymphadenectomy (EPD) during pancreatoduodenectomy may improve staging and reduce recurrence, but its survival benefits over standard lymphadenectomy (SPD) remain controversial. Methods: A systematic search of PubMed, Embase, Web of Science, and the Cochrane Library was conducted on March 25, 2025. All studies that met the inclusion criteria were subjected to quality assessment and subsequently analyzed by meta-analytical methods. Results: Nine RCTs involving 1382 patients were analyzed. No significant differences were observed between EPD and SPD in OS (HR = 1.09, Conclusions: EPD reduces lymph node recurrence without improving OS or DFS, suggesting limited prognostic benefit. Its application in pancreatic cancer should be carefully considered. Systematic review registration: https://www.crd.york.ac.uk/prospero, identifier CRD42024594566.
