Overall, 90\u2010day complications occurred in 475 (22.3%) patients, including infection (10%), hematoma (6%), delayed healing (4.1%), seroma (3.9%), and flap compromise (2.8%). AUCs ranged from 0.60 to 0.66 (logistic regression) and 0.64 to 0.73 (ML). Higher BMI was associated with increased risk for seroma (OR: 1.1, 95% CI: 1.04\u20131.13) and neoadjuvant chemotherapy for infection (OR:1.72, 95% CI: 1.17\u20132.51). Key ML model predictors on SHAP analysis included age, BMI, and pre\u2010reconstruction radiation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Individualized risk prediction models for complications after autologous breast reconstruction were developed using traditional statistics and ML.
