Four ML algorithms (extreme gradient boosting, random forest, logistic regression, and support vector machine) were integrated to identify the optimal model, and Shapley Additive exPlanations (SHAP) interpretation was used for visual explainability. Two models were established to forecast the response to UST, with the outcomes of the response situation at week 26 and secondary loss of response (sLOR) status at week 52, respectively. Eighty-two CD patients from the other five centers were applied for the week-26 model\u2019s external validation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>XGBoost performed excellently among the four ML algorithms. The week-26 model exhibited good performances of 0.88 area under the receiver operating characteristic curve (AUC), 0.92 area under the precision-recall curve, and 0.86 F1 score.
