Median pro-inflammatory cytokine measurements throughout the study period. Whiskers indicate IQR. T0, induction of anaesthesia; T2, end of cardio-pulmonary bypass; T3, 6 h after the end of cardio-pulmonary bypass; and T4, 24 h after the end of CPB. IL interleukin; IFN-γ, interferon-gamma; MCP-1, monocyte chemoattractant protein-1; TNF-α, tumour necrosis factor-alpha. Inter-group comparisons performed using the Mann-Whitney U test comparisons at each time point. Effect of time within each group was significant (Kruskal-Wallis one-way analysis of variance) for all measurements (p < 0.05) except for IFN-γ in the control group (p = 0.09) and IL-2 in the control (p = 0.232)
