  1. p value: Mann–Whitney U test. Measurements were recorded on the day of the RI manoeuvre. If there were no measurements for IL-2 and IL-6 at the RI manoeuvre day, last valid measurements were recorded. If there was more than one measurement during the day, the mean value was calculated
  2. IQR interquartile range, CRP C-reactive protein, ECLIA electrochemiluminescence immunoassay, IL interleukin, RI recruitment to inflation ratio, SAPS simplified acute physiology score
