Performance of mean arterial pressure to predict acute kidney insufficiency (AKI) at H72. The areas under the receiver operating characteristics curves (AUC) of time-averaged MAP over H6 to H24 (left panel) and over H12 to H24 (right panel) to predict acute kidney insufficiency (AKI) at H72 was examined in four subgroups of patients: patients with no AKI at H6 and non septic shock (black thin line), patients with no AKI at H6 and septic shock (dashed thick line), patients with AKI at H6 and non septic shock (dashed thin line), and patients with AKI at H6 and septic shock (black thick line). In this latter subgroup, the AUC (see values in Table 3) was significantly higher than in the three others subgroups for time-averaged MAP over H6 to H24 (left panel) (P = 0.0037 vs the no AKI at H6 and septic shock patients; P = 0.0037 vs the no AKI at H6 and non septic shock patients; P = 0.02 vs the AKI at H6 and non septic shock patients) and over H12 to H24 (right panel) ((P = 0.0065 vs the no AKI at H6 and septic shock patients; P = 0.002 vs the no AKI at H6 and non septic shock patients; P = 0.036 vs the AKI at H6 and non septic shock patients).
