Differentially expressed miRNA by tumor subtype. Bar chart describing relative expression levels for each subgroup relative to the average expression level in normal tissues. Error bars represent the standard error. (A) miRNA with highly significant differences between dMMR and pMMR tumors. (B) Tumor significant miRNA with p < 0.05 and a fold change > 1.5 for the comparison of dMMR and pMMR tumors. (C) Tumor significant miRNAs with p < 0.05 and fold change > 1.5 for the comparison of pMMR stage II and pMMR stage IV tumors.
