Changes in jugular venous oxygen saturation (SjvO2) (white box plots) within pre-defined arterial blood glucose clusters. Changes in SjvO2 were significantly increased at arterial blood glucose levels above 8 mmol/l compared with lower arterial blood glucose levels. *p < 0.001; analysis of variance (ANOVA) on ranks and post hoc Dunn's test. Calculated oxygen extraction ratio (OER) (grey box plots) within pre-defined arterial blood glucose clusters was significantly decreased at arterial blood glucose levels above 8 mmol/l compared with lower arterial blood glucose levels. *p < 0.001; ANOVA on ranks and post hoc Dunn's test.
