- The table shows the number of samples that were analyzed per age group, the topographic location of the samples (SI = small intestine, D = duodenum, J = jejunum, I = ileum), and whether they were mucosal biopsies and full-thickness resections. For age groups 5 and 6, parallel samples were available from two different regions of the small intestine. These were used to check for the effect of location on enzyme expression, but only one sample per patient was taken into account for the statistical analysis. This is the reason for the discrepancy between "# of samples" (marked by an asterisk) and the sum of all samples listed under "Sample origin".
