    A prehabilitation-enhanced nomogram was developed to predict early postoperative pulmonary recovery failure after lung tumor surgery.

  • 2

    The study utilized a multicenter retrospective design with a development cohort and an external validation cohort.

  • 3

    Five predictors were included in the final nomogram: intraoperative blood loss, DLCO% predicted, preoperative resting SpO2, and two target-achieved days.

  • 4

    The nomogram demonstrated improved discrimination, with AUCs increasing significantly across training and validation cohorts.

  • 5

    Calibration was acceptable, and decision curve analysis indicated the nomogram's clinical usefulness for risk stratification.
