Summary of Research on AAV-ILD Prognostic Nomogram
What’s New: A novel nomogram model has been developed to predict the prognosis of patients with Antineutrophil cytoplasmic antibody vasculitis-associated interstitial lung disease (AAV-ILD), incorporating factors such as cardiac involvement, albumin levels, smoking history, and age.
Importance: This research addresses the gap in understanding the mortality risk associated with AAV-ILD by identifying key prognostic factors and creating a predictive tool.
Contribution to Literature: The study introduces a predictive nomogram with high performance metrics, including a Harrell’s C index of 0.826 and an area under the receiver operating characteristic (ROC) curve (AUC) of 0.940. It outperforms the existing ILD-GAP model in terms of discrimination and calibration, as evidenced by integrated discrimination improvement (IDI), net reclassification improvement (NRI), and likelihood ratio test results.
Results: The study involved 192 patients, with a mortality rate of 32.29% during the observation period. The nomogram’s calibration curves aligned closely with actual outcomes. Decision curve analysis (DCA) confirmed the model’s superior predictive value. Internal validation yielded a mean Harrell’s C-index of 0.815, suggesting the model’s reliability.
Future Directions: The study suggests that external datasets could be used for further validation of the nomogram model.
