Identifying recurrence-related prognostic indicators. a Volcano plot exhibiting the distribution of DEGs via log2(fold-change) and P values. b Sample clusters showing basic clinical information on HCC patients. c Soft threshold power selection for gene clustering; a value of 7 was selected as the threshold. d In total, 13 gene modules were discovered via gene clustering. e Heatmap exhibiting the relationship between different gene modules and clinical risk factors (Pearson correlation). Blue modules were the most relevant to recurrence and OS. f Plot showing 34 genes in blue modules and their coexpression relationships
