Participants were randomly assigned into training and validation sets in a 7:3 ratio (training set, n\u2009=\u2009881; validation set, n\u2009=\u2009378). Least absolute shrinkage and selection operator regression combined with multivariate logistic regression were employed to identify independent predictors and construct a nomogram model. The model was validated through receiver operating characteristic curve analysis, calibration curves, and decision curve analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Four independent predictors were identified: age, total cholesterol level, serum urea nitrogen level, and white blood cell count.

Calibration curves revealed high concordance between predicted probabilities and observed outcomes.
