The gene modules associated with chronic pancreatitis (CP) and pancreatic ductal adenocarcinoma (PDAC), as identified using weighted gene co-expression network analysis, are depicted here. (a) Interconnections among the network genes show scale-free network distribution at a soft threshold power (β) of 16 (scale-free R2 = 0.89). (b) The dendrogram indicates the classification of genes into distinct modules according to correlation analysis. Each color represents a module, and the gray module includes genes that are not assigned to a particular network. (c) The heatmap of module trait relationships shows the association of various gene modules with the clinical status. (d) The potential lncRNA–miRNA–mRNA regulatory network is shown
