The prediction model demonstrated excellent discrimination with an area under the ROC curve (AUC) of 0.956, sensitivity of 0.910, and specificity of 0.864. External validation yielded an AUC of 0.938, sensitivity of 0.833, and specificity of 0.821.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
