Neutrophil-albumin ratio and multi-phase computed tomography for lymph node metastasis in pancreatic cancer.
Article in World journal of gastrointestinal oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundReliable preoperative detection of lymph node metastasis (LNM) in pancreatic cancer remains elusive: Conventional computed tomography (CT) underestimates micrometastases, and carbohydrate antigen 19-9 is hampered by low specificity. The neutrophil-albumin ratio (NAR) simultaneously reflects systemic inflammation and nutritional depletion, but its contribution to LNM prediction in pancreatic cancer is unexplored. We hypothesised that integrating NAR with multi-phase CT findings would significantly improve the accuracy of preoperative LNM assessment in patients undergoing curative-intent resection.
aimTo determine whether preoperative NAR plus multi-phase CT reliably predicts nodal metastasis in pancreatic cancer.
methodsIn this single-centre retrospective cohort study (February 2022 to February 2025, Ordos Central Hospital, China), 129 consecutive patients undergoing curative pancreatic resection were histologically classified as LNM
resultsBetween the two cohorts, univariate comparison revealed significant divergence in age, tumour diameter, concomitant hemangioma thrombosis, PAR, NAR, and CT-detected nodal status (
conclusionThe model 3 (NAR > 0.13, PAR > 6.35, CT nodal positivity, hemangioma thrombosis) provides robust, clinically actionable preoperative identification of pancreatic cancer patients at high risk of LNM.
