(A) Relationship between the arterial and venous ammonia concentration showing the line of identity and the regression line (slope 0.75 ± 0.05 and is ≠ 1) for the cerebral ammonia extraction. (B) Scatterplot between arterial ammonia and net cerebral ammonia uptake in patients with FHF.

3. Fig. 2
The mean cerebral glutamine-nitrogen efflux in patients with FHF during normoventilation (I) and hyperventilation (II), in patients with cirrhosis of the liver and in healthy subjects (ANOVA on Ranks, P < 0.05). Dashed areas shows the maximal cerebral glutamine efflux (mean) that can be explained by cerebral ammonia uptake.

Boxplot showing the median, 10th, 25th, 75th, and 90th percentiles as vertical boxes with error bar of arterial ammonia concentration (P = 0.002), net cerebral ammonia uptake (P = 0.02), and net cerebral glutamine efflux (P = 0.02) in survivors compared with nonsurvivors.
