Neutrophils can serve as predictive risk factors for AS in clinical settings. (A-C) Results obtained from the RF, LASSO and SVM algorithm respectively. (D) The intersection of the four screening methods yielded five risk factors. (E) A dynamic prediction model was established using the selected parameters: PCTE, Pdw, NEUT, GRAN and Age. The red line represents the probability of AS occurrence at different values. (F-H) Calibration curve, ROC curve and clinical impact curve in the test group respectively. (I-K) Calibration curve, ROC curve and clinical impact curve in the verification group respectively.
