Age distribution of patients in each group and test results of patients in each group. (A) Age distribution results of FRI and Non-FRI patients. Green represents the age distribution of adolescent patients with FRI, comprising 864 patients. Black represents the age distribution of middle-aged patients with FRI, comprising 1766 patients. Blue represents the age distribution of the elderly with FRI, comprising 2131 patients. Additionally, brown represents a group of adolescents with Non-FRI, consisting of 921 patients. Purple represents middle-aged patients with Non-FRI, totaling 1842 patients. Lastly, yellow represents the elderly with non-FRI, including 1998 patients. (B–G) represent the evaluation metrics of the test set for each age group used by RF, BP, SVM, XGBoost, and TSDPSO-SVM. These metrics include the area under the curve (AUC), recall, specificity, false positive rate (FPR), precision, and F1 score.
