Figure 3. Analysis of the weighted co-expression network in GSE171110. (A) Sample clustering of dataset GSE171110. (B) The relationship between the scale-free fit index and various soft-thresholding powers; the relationship between the mean connectivity and various soft-thresholding powers. (C) Clustering dendrogram of genes, various colors represent different modules. (D) Analysis of correlations between modules and COVID-19. The blue module and brown module were significantly correlated with COVID-19 and normal samples.
