Schematic diagram of the six phases of the study protocol. F, bilateral FBF measurements each for 3 min; *, time for blood sampling; #, time for assessment of systemic hemodynamics using electrical bioimpedance. ANG-II doses are 3, 10 and 30 pmol min−1. The l-NMMA dose is 4 μmol min−1. SNP was infused at titrated doses ranging from 80 to 600 ng min−1.

Percentage change in FBF in response to l-NMMA infusion (4 μmol min−1) in cirrhotic patients (□) and controls (○). P<0.001 from baseline 1 in both groups. P>0.05, cirrhotic patients vs. controls, two-way ANOVA with replication.

FBF responses to incremental doses of ANG-II (pmol min−1) in cirrhotic patients (squares) and controls (circles) before the ‘NO-clamp’ (open symbols) and during the ‘NO-clamp’ (solid symbols). P<0.001, dose–response in each phase by one-way ANOVA. Cirrhotics vs. controls: P=0.012 before clamp; P=0.57 during clamp (two-way ANOVA with repeated measures). Before clamp vs. during clamp: P<0.001 in cirrhotics; P=0.75 in controls (two-way ANOVA with repeated measures).
