Correlation coefficients (r) for the plots of LBTT and MCTT versus the proportions of cholic, deoxycholic, chenodeoxycholic, ursodeoxycholic, and lithocholic acids, expressed as percentages of total serum bile acids, total conjugated serum bile acids, and total unconjugated serum bile acids.
MCTT, mouth to caecum transit time; LBTT, large bowel transit time.
