Prognostic value of the combined fibrinogen and prognostic nutritional index score in resectable gastric cancer.
Article in Frontiers in 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
Objective: This study aimed to evaluate the prognostic value of the preoperative fibrinogen and prognostic nutritional index (PNI) combination score (F-PNI) in predicting long-term survival following radical gastrectomy in patients diagnosed with resectable gastric cancer. Methods: A retrospective cohort analysis was performed using clinicopathological and follow-up data from 491 patients who underwent radical gastrectomy for gastric cancer at a single tertiary institution between January 2012 and December 2017. Statistical analyses were conducted using SPSS version 25.0 to identify independent prognostic factors associated with five-year overall survival. Results: The optimal preoperative cut-off values were identified as 3.335 mg/L for fibrinogen and 52.7 for the PNI. The area under the receiver operating characteristic curve (AUC) for the F-PNI score was 0.633, demonstrating higher discriminative ability compared to PNI alone (AUC = 0.592) and fibrinogen alone (AUC = 0.587). Kaplan-Meier survival analysis showed five-year survival rates as follows: low vs. high fibrinogen levels, 72.9% vs. 56.4%; high vs. low PNI, 82.6% vs. 58.0%; and F-PNI score 0, 1, and 2, 87.8%, 66.9%, and 50.0%, respectively. Both univariate and multivariate Cox proportional hazards models identified a high F-PNI score, advanced age, pathological TNM stage IIIA-IIIC, and vascular invasion as independent prognostic factors for five-year survival. The F-PNI score demonstrated superior prognostic performance compared to either fibrinogen or PNI alone. Conclusion: The F-PNI combination score is an independent prognostic marker for long-term survival in patients undergoing radical resection for resectable gastric cancer. Its enhanced predictive accuracy relative to fibrinogen or PNI individually suggests potential utility in preoperative prognostic stratification.
