Evolution of mean transit time (mTT) (a), perfusion index (PI) (b) and rBV (c) during the first 3 days in ICU in patients with septic shock with acute kidney injury (AKI) Kidney Disease Improving Global Outcome (KDIGO) stage 2 or 3 (AKI+) or in patients with septic shock without AKI or with AKI KDIGO stage 1 (AKI-); a.u., arbitrary units. **p = 0.005 for group effect (with AKI or without AKI) with analysis of variance (ANOVA) on ranks. rBV ANOVA (p = 0.49). Box plots show median, interquartile (1;3) and maximum values
