Receiver operating characteristic curves for prediction of severe acute kidney injury ( Kidney Disease Improving Global Outcome (KDIGO) stage 2 or 3) during the first 72 h with microhemodynamic data (mean transit time measured with contrast enhanced ultrasound (mTT), perfusion index measured with contrast enhanced ultrasound (PI), resistivity index measured with Doppler ultrasonography (RI)) and macrohemodynamic data (cardiac index)
