Research on risk assessment and predictive model for gastrointestinal fistula after gastrectomy based on F-index scoring system.
Article in BMC gastroenterology, 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
backgroundGastrointestinal fistula is a serious complication after gastrectomy, leading to high morbidity and mortality. Early identification of high-risk patients is crucial for improving outcomes and reducing complications. However, a simple and effective scoring system for assessing postoperative fistula risk is still lacking.
methodsThis multicenter retrospective study aimed to develop and validate a scoring system (F-index) for predicting gastrointestinal fistula risk after gastrectomy. A total of 83 patients diagnosed with postoperative gastrointestinal fistula after gastrectomy between Aug 2021 and Dec 2023 were included. Patients were divided into low-risk (0–3 points, 30 patients) and high-risk (4–7 points, 53 patients) groups. 58 patients from the Third Hospital of Jilin University were used as the training set, while 25 patients from Weifang People’s Hospital formed the validation set. Data collection included demographic information, surgical data, and postoperative outcomes. Univariate and multivariate logistic regression analyses were used to identify risk factors, and ROC curve analysis was performed to evaluate the F-index’s predictive performance. Sensitivity, subgroup analyses, and nomogram construction were also conducted to validate the model.
resultsThe F-index showed good discriminatory ability for post-diagnosis risk stratification among patients with postoperative gastrointestinal fistula after gastrectomy. Multivariate analysis indicated that time to fistula recognition after surgery > 7 days (OR = 6.307, 95% CI: 1.343–29.619, p = 0.020) and fistula diameter > 1 cm (OR = 0.109, 95% CI: 0.023–0.520, p = 0.005) were independently associated with high-risk classification. ROC curve analysis demonstrated an AUC of 0.79 (95% CI: 0.528–0.972) for the training set and 0.75 (95% CI: 0.267–1.000) for the validation set. Sensitivity and subgroup analyses showed consistent performance across different age and BMI thresholds, and the calibration plot indicated good agreement between predicted and observed risks.
conclusionThe F-index scoring system is a simple and effective tool for post-diagnosis risk stratification in patients with postoperative gastrointestinal fistula after gastrectomy, helping identify high-risk cases and optimize postoperative management.
