Figure 4From: Differential influence of arterial blood glucose on cerebral metabolism following severe traumatic brain injuryOxygen-glucose index (OGI) was significantly increased compared with normal values. This is reflected by the straight line at 6. With increasing arterial blood glucose concentrations OGI was significantly decreased compared with lower arterial blood glucose levels. *p < 0.001; analysis of variance (ANOVA) on ranks and post hoc Dunn's test.Back to article page
