    This study involved 102 patients with microbiologically confirmed mycobacterial lung disease, including 53 with MTB-LD and 49 with NTM-LD.

    An interpretable multimodal machine-learning framework was developed, integrating clinical symptoms, biomarkers, and HRCT features for disease differentiation.

  • 3

    The random forest model outperformed other classifiers, achieving an AUC of 0.92, sensitivity of 0.89, specificity of 0.93, and F1-score of 0.90.

    Key predictive contributors for differentiating MTB-LD from NTM-LD included cystic bronchiectasis, tree-in-bud sign, fever, and specific laboratory biomarkers.

  • 5

    The study emphasizes the need for external validation before clinical implementation of the proposed multimodal diagnostic framework.
