Pearson’s correlation coefficients (PCCs) of expression levels of each lncRNA-PEG pair within the Blue module were computed and clustered. In the resulting heatmap, the PCCs of each of the five lncRNAs with the 304 PCGs were plotted in a separate row. The color scale on the right shows PCC value from 0 (blue) to 1 (red), where blue represents no correlation, and red a perfect positive one. Euclidean distances were used for the clustering analysis
