PPCs included pneumonia, pleural effusion, pneumothorax, atelectasis, respiratory failure, aspiration, acute respiratory distress syndrome, tracheobronchial fistula, and persistent air leakage. Univariable and multivariable logistic regression with backward selection were used to identify predictors. Model performance was assessed with the area under the receiver operating characteristic curve (AUC). Statistical significance was set at P\u2009&amp;lt;\u20090.05.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Among 960 patients, 254 (26.5%) developed at least one PPC. Independent predictors were smoking status (former: OR 1.45, 95% CI 1.03\u20132.06; current: OR 1.74, 95% CI 1.15\u20132.63), non-epidural analgesia (paravertebral: OR 1.50, 95% CI 1.03\u20132.17; other: OR 1.57, 95% CI 0.88\u20132.82), and cervical versus intrathoracic anastomosis (OR 1.64, 95% CI 1.17\u20132.29). Drain configuration also influenced the risk of PPC: one-sided double drains were protective (OR 0.48, 95% CI 0.25\u20130.91), whereas bilateral drains increased the risk (OR 2.60, 95% CI 1.38\u20134.87), compared with one-sided single drains. The model demonstrated modest discrimination after validation of AUC: 0.598.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Smoking, paravertebral analgesia, cervical anastomosis, and bilateral drains were independently associated with increased PPC risk. Although predictive performance was modest, these modifiable and structural factors inform perioperative management.
