the results suggest that ( a ) direct measurements confirm the accuracy of indirect estimates of hepatic extraction of chenodeoxycholic acid , ( b ) hepatic extraction of chenodeoxycholic acid is lower than that of cholic acid and glycocholic acid , but higher than that of ursodeoxycholic acid , ( c ) progressive impairment of the extraction ratios of these two bile acids occurs as the severity of liver disease increases , and ( d ) the ratios are correlated with indocyanine green extraction ratios .
