<i>ABCC2</i> mRNA levels x 10⁷ in intestinal tissues normalised to 18S RNA level.

a P-values for comparison of the expression levels to the level in controls adjusted for age and gender. b P value for the comparison of the expression levels in the morphologically affected and unaffected tissues from the same individual using Paired Student’s t-test. Matching samples were available from 66 cases with mild-moderate dysplasia, 11 cases with severe dysplasia, and 63 and 66 CRC cases (distant unaffected tissue and adjacent unaffected tissue, respectively). ABCC2 mRNA levels x 107 in intestinal tissues normalised to 18S RNA level.
