  1. Data are expressed as medians with 25th and 75th percentiles
  2. CI cardiac index, MAP mean arterial pressure, PPI peripheral perfusion index, ScvO2, central venous oxygen saturation
  3. *p < 0.05 between groups A and B at that time point
  4. #p < 0.05 versus baseline (T0) value in the same group
