Fig. 2From: Determinants of Doppler-based renal resistive index in patients with septic shock: impact of hemodynamic parameters, acute kidney injury and predisposing factorsDistribution of renal resistive index at day 1 (RI D1) according to AKIN classification at day 3 (AKIN D3). RI D1 corresponds to the mean of RI measured for each patient at different mean arterial pressure levels over a period of 20 min on the ICU admission day. Horizontal lines represent median, first and third quartile values for each group. Overall comparison: p = 0.01Back to article page
