Measurement of hepatic functional mass by means of 13C-methacetin and 13C-phenylalanine breath tests in chronic liver disease: Comparison with Child-Pugh score and serum bile acid levels

Figure 1 Methacetin and phenylalanine breath tests: cumulative percent of oxidation at 60 and 120 min. A: Methacetin breath test: cumulative percent of oxidation at 60 and 120 min. CTR = controls; CH = chronic hepatitis; LCA = liver cirrhosis Child A; LCB = liver cirrhosis Child B; LCC = liver cirrhosis Child C. CTR vs CH, LCA, LCB, LCC: P<0.001 CH vs LCA, LCB, LCC: P<0.001 LCA vs LCB, LCC: P<0.001 LCB vs LCC: P<0.001. B: Phenylalanine breath test: cumulative percent oxidation at 60 and 120 min. CTR = controls; CH = chronic hepatitis; LCA = liver cirrhosis Child A; LCB = liver cirrhosis Child B; LCC = liver cirrhosis Child C. CTR vs LCB, LCC: P<0.001 CH vs LCB, LCC: P<0.001 LCA vs LCC: P<0.05.
