Table 2

Comparison of residual solid stool and residual fluid in the colonic segments between right and left colon independent of the dietary regimens.

Right colon: caecum, ascending colon, and transverse colon; left colon: descending colon, sigmoid colon, and rectum.
^**The left colon was significantly better prepared than the right colon for residual solid stool and residual fluid, independent of the diet regimens (P < 0.01).
