Figure 8

Circulating blood glucose and its relationship to dolorimetric measures of pain threshold. Values depict the mean ± SEM concentration of glucose measured in blood samples taken immediately prior to CT scans of both groups after exposure to warm and cold environments (A). These values were compared using ANOVA using a cutoff of P < 0.05 for significance, as indicated by the asterisk. Individual changes in values for glucose (B) reflect the difference in concentrations between warm and cold environments. Using Pearson’s correlational analyses, these glucose values were compared within groups to their corresponding pain assessments obtained when tested by dolorimetric analyses (as used in figure 1). Correlation coefficients (R) and P values were calculated for each group with a P < 0.05 as the cutoff for significance.
