Three Ishii score trajectories were identified: low-risk (40.5%), moderate-risk (36.7%), and high-risk (22.7%). Older age (OR 1.08), lower preoperative BMI (OR 0.81), lower preoperative FEV1%pred (OR 0.97), longer ICU stay (OR 1.11), and a higher NRS 2002 score (OR 1.39) were independently associated with the high-risk trajectory (all\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.05).
