Sample groups, Fold-Changes (FC) and transcript classes. Transcript classes defined on the basis of four indices (FC1, FC2, FC3, FC4), three CRC groups (All CRC, Control CRC, Selected CRC) and one Normal Colonic Mucosae group (Normal). CRCs with specific BGA form a “Selected CRC” group while CRC without specific BGA form a “Control CRC” group. Fold-changes (FC) are obtained by comparisons of RMA averages between different groups: FC1 between “all CRC” and “Normal”, FC2 between “Selected CRCs” and “Control CRCs”, FC3 between “Control CRC” and “Normal”, FC4 between “Selected CRC” and “Normal”.
