¹The five microRNAs differentially modified both in tissue and plasma show the same trend in term of fold change.

²Tissue, paired analysis (19 tumoral tissue vs 19 peritumoral tissue).

³Plasma case-control (19 colorectal cancer plasma vs 16 control plasma).

T: Tumoral; PT: Peritumoral; CTRL: Control; CRC: Colorectal cancer; FC: Fold change; NS: Not significant.
