Utilizing WGCNA to obtain key modules.

(A)Identification of co-expressed gene modules. A dendrogram of all differentially expressed genes was clustered based on a measure of gene similarity. Cut lines of modules were identified, and a different color indicated each module. (B) Heat map of the correlation between modules and clinical phenotypes. module and the clinical phenotype. The corresponding cor value and p-value are labeled therein. The brown modules have the strongest correlation with PD.
