Correlation analysis between differential methylation sites and other clinical indicators. Correlation analysis between differential methylation sites and clinical indicators. a. CpG sites positively associated with the mMRC score (0–4). p-value< 0.05. The methylation differences at 23 sites between different mMRC groups are presented in the clustering map. b ROC curve of acute exacerbation frequency p-value < 0.05, AUR > 0.5. c ROC curve of CAT score. p-value < 0.05, AUR > 0.5
