From: Phosphodiesterase-5 inhibitors have distinct effects on the hemodynamics of the liver
Course of relative changes of hepatic hemodynamic parameters after slow intravenous injection of 10 μg/kg sildenafil or 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. Significant changes at 60 min (p < 0.05; Wilcoxon rank sum test) are marked with black stars. Panel 1: Hepatic arterial flow. Panel 2: Parenchymal flow. Panel 3: Fractional liver flow.
