4. Figure 3
Percentage change of RI compared to baseline value after first and second dopamine infusion. A close linear relationship between both values (r=0.74, P<0.0001) indicates high reproducibility of the effect of dopamine.

5. Figure 4
Intraindividual comparison and mean±s.d. of RI values during placebo and dopamine infusion in patients with and without ARF. In patients without ARF dopamine reduced the RI significantly (P<0.01, Wilcoxon test), whereas there was a significant increase in patients with ARF (P<0.01).

Schematic presentation of the study design. All patients received ‘low-dose’ dopamine or placebo for two periods of 1 h in alternating sequence and were randomly assigned to two groups receiving either dopamine or placebo first.
