May aid preoperative risk assessment after gastrectomy; leaves open prospective validation before clinical use.
Do machine learning models improve the prediction of 30-day postoperative mortality following gastrectomy compared to simple logistic regression?
Machine learning models, particularly XGBoost, provide superior prediction of 30-day mortality after gastrectomy compared to traditional logistic regression.
