Development and Validation of an Explainable Machine Learning Model for Identification of Dysphagia in Patients with COPD.

Although mMRC grade 2 and grade 4 were not statistically significant ( P = 0.183 and P = 0.078, respectively), and muscle strength grading did not reach statistical significance (all P > 0.05), these variables were retained in the final model due to their contribution to overall model fit based on AIC-driven stepwise regression.
