Identification of differentially expressed RNAs (DERs). a Volcano map. Blue dots indicate DERs, the red horizontal dotted line represents false discovery rate (FDR) < 0.05, the two red vertical dotted lines represent the |log fold change (FC)| > 0.263. b A bidirectional hierarchical clustering map based on DERs. White and black sample bars represent recurrence and non-recurrence colon adenocarcinoma samples, respectively
