Predictive model for anemia in elderly patients. (A) The predictive model demonstrated promising performance in estimating the likelihood of anemia in elderly patients, with AUC values of 0.955 (95% CI 0.939–0.971. (B) The calibration plot indicates good alignment between predicted and observed probabilities, with a calibration slope of 0.97 and intercept of 0.03. The Brier score of 0.086 further confirms model accuracy. (C) The DCA analysis highlights the net benefit of using the predictive model across a range of threshold probabilities. (D) The clinical impact curve illustrates the effective stratification of patients, with a higher number of correct anemia predictions at different risk thresholds.
