Risk factors analysis and nomogram model construction of refeeding syndrome after esophageal cancer surgery.
Article in Frontiers in oncology, 2026. 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
Background: To construct and verify the risk prediction nomogram model of postoperative refeeding syndrome (RFS) in patients with esophageal cancer, and to provide a basis for early identification of high-risk groups and development of individualized nutritional intervention strategies. Methods: A retrospective observational study design was used. Patients who underwent esophageal cancer surgery in a Grade A tertiary hospital in Shanghai from January 2023 to August 2024 were selected as the modeling group, and patients who underwent esophageal cancer surgery from September 2024 to June 2025 were selected as the validation group. RFS was diagnosed according to the criteria of the American Society of Parenteral and Enteral Nutrition. Independent risk factors were screened by univariate analysis and multivariate logistic regression, and a nomogram model was constructed based on significant variables. Bootstrap method was used for internal validation, and independent validation group was used for external validation. The area under the receiver operating characteristic curve (AUC), Brier score, Hosmer-Lemeshow test and decision curve analysis (DCA) were used to evaluate the discrimination, calibration and clinical effectiveness of the model. Results: The total incidence of RFS was 21.74% (100/460), 22.26% (69/310) in the modeling group and 20.67% (31/150) in the validation group. Multivariate analysis showed that age, diabetes mellitus, prealbumin before feeding, albumin before feeding, parenteral nutrition support and rapid enteral feeding were independent risk factors ( Conclusion: The nomogram model constructed in this study integrates core predictive factors such as age, history of diabetes, pre-feeding albumin level, nutritional support method and speed. It shows good predictive efficacy in both the internal and external validation cohorts and can provide a quantitative tool for the early screening and individualized nutritional management of patients at high risk of RFS after esophageal cancer surgery.
