Identification of Key Modules, Hub Genes, and Noncoding RNAs in Chronic Rhinosinusitis with Nasal Polyps by Weighted Gene Coexpression Network Analysis

Figure 6

(a) Identification of the best inflection point based on the sum of the squared error (SSE). K = 4 is the optimal value. (b) The clustering of chronic rhinosinusitis with nasal polyps (CRSwNP) samples. It was possible to divide all the CRSwNP samples into four phenotypes, represented here by different colors. (c) Expression heatmap of genes coexpressed in CRSwNP. (d) Expression heatmap of coexpressed hub genes in the four subtypes of CRSwNP.
