Fig 3 Postoperative renal regional oxygen saturation ( r S O 2 ), microcirculation (rFlow), renal oxygen consumption (aRMRO2), and renal resistance index (RRI) in patients after surgical repair without acute kidney injury (AKI; Group 1), patients after surgical repair who developed AKI (Group 2), patients with surgical palliation without AKI (Group 3), and patients with surgical palliation who developed AKI (Group 4). *P-values <0.05 were considered statistically significant. The y-axis does not start at zero; the absolute differences may therefore appear larger than they really are.
