Course of relative changes of portal flow and portal pressure after slow intravenous injection of different doses of sildenafil, vardenafil, or 0.9% NaCl. Ordinate: time (minutes) Abscissa: relative change (e.g. 0.00 means baseline; 0.10 means: increase by 10%; -0.10 means: decrease by 10%). The values are indicated as mean ± 95% confidence intervals. Panel 1: Portal flow. Panel 2: Portal pressure. The values are indicated as mean ± 95% confidence intervals. The curves at different doses are marked by colours.
