Implication

Randomized trial demonstrates accurate prediction of clinically significant improvement in patients undergoing lumbar fusion surgery, suggesting improved decision-making support.

Key Points

The aim is to develop a machine learning model that predicts clinically significant improvement after lumbar fusion surgery using preoperative factors.
Included 359 patients who underwent lumbar fusion surgery between January 2021 and December 2023.
Evaluated 22 preoperative variables and used a multi-label classification approach.
Assessed model performance with 5-fold cross-validation and seven evaluation metrics, focusing on F1-score and AUROC.
The Extra Trees model achieved an F1-score of 0.850 and AUROC of 0.835.
Key predictors identified included hypertension, diabetes mellitus, body mass index, bone mineral density, and revision status through SHAP analysis.
Postoperative complications were analyzed for associations with comorbidities and outcomes.
