Delta SOFA score, fluid intake, and cumulative FB at day 5 according to FO status. Delta SOFA score from day 0 to day 5 was higher in the group of patients without FO compared to the group of patients with FO (mean delta SOFA score: 4.52 (+/− 3.74) vs. 2.15 (+/− 3.50), p < 0.001). Fluid intake at day 5 was more important in the FO group, with a between-group difference of 5709 ml (11,171 ml vs. 16,880 ml, p < 0.001). Cumulative fluid balance at day 5 was more important in the FO group, with a between-group difference of 5977 ml (2738 vs. 8715 ml, p < 0.001)
