Data presented as mean ± standard deviation or number (%). Main characteristics at inclusion are shown. During the follow-up period, the SOFA evolution within 4 days was also associated with higher mortality rates. MAP, mean arterial pressure; PcvaCO2 gap, central venous-to-arterial carbon dioxide difference; PcvaCO2/CavO2 ratio, central venous-to-arterial carbon dioxide difference/arterial-to-central venous oxygen content difference ratio; SAPS, Simplified Acute Physiological Score; ScvO2, central venous oxygen saturation; ΔSOFA, SOFA score at day 4 – SOFA score at day 1; SOFA, sequential Organ Failure Assessment.
