A multivariable logistic regression model was developed using a randomly selected training cohort (70%;\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20094,835) and internally validated in an independent testing cohort (30%;\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20092,092). Model performance was evaluated for discrimination using the area under the receiver operating characteristic curve (AUC), calibration using calibration plots and the Hosmer\u2013Lemeshow goodness-of-fit test, and stability via bootstrap resampling (1,000 replications).

The final model included predictors such as age, gender, nationality, body mass index, smoking, physical activity, sleep duration, diabetes, hyperlipidemia, and cardiovascular diseases. The model demonstrated good discrimination, with AUCs of 0.803 (95% CI: 0.78\u20130.83) and 0.797 (95% CI: 0.76\u20130.84) in the training and testing cohorts, respectively. Calibration was satisfactory, with close agreement between predicted and observed outcomes and non-significant Hosmer\u2013Lemeshow tests in both the training (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.102) and testing (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.393) cohorts. Bootstrap bias across all predictors was negligible, further supporting the model's stability.
