    Postoperative atrial fibrillation (POAF) is a significant complication after lung cancer surgery, affecting 19.8% of patients in the study.

  • 2

    Six predictors of POAF were identified: age, education level, hypertension, marital status, postoperative pain score, and surgical approach.

  • 3

    Logistic regression (LR) showed the highest stability and accuracy in predicting POAF, with an AUC of 0.855 in the test cohort.

  • 4

    A nomogram based on the LR model was developed to provide individualized risk estimation for POAF in lung cancer surgery patients.

  • 5

    The study demonstrates the potential of machine learning techniques to improve risk stratification and clinical decision-making for POAF.
