Retrospective study developed machine learning models for mortality prediction in hemodialysis patients, highlighting risk stratification importance.

Gradient boosting models outperformed others in mortality prediction for hemodialysis patients, indicating strong model effectiveness.
XGBoost achieved an F1 score of 0.683 and a ROC AUC of 0.899, showcasing its predictive capabilities in this population.
The study employed a systematic approach with data split into 70% training and 30% testing for robust model validation.
Clinical implementation of optimized models could enhance the identification of high-risk individuals and improve patient outcomes.],

Chen et al. (2025) studied this question.
