Weighted gene co-expression network analysis. A Sample clustering dendrogram with tree leaves corresponding to individual samples. B The scale-free fitting index (R2) and average connectivity at different soft threshold power were analyzed. C The initialized and integrated modules under the clustering tree. D Collinear heat map of module key genes. Red means a high correlation, blue means a low correlation. E Clustering dendrogram of module key genes. F Heat map of module–trait correlations. Red indicates a positive correlation and blue indicates a negative correlation. G, H The frontal correlation between clinical features and yellow module (G), and turquoise module (H)
