Fig. 5. Scatterplot illustrating the relationship between ipsilateral paw withdrawal thresholds and glycemia in rats with chronic postischemia pain (CPIP) using glucose levels for the entire ischemia-reperfusion injury (A ), for only the ischemic period (B ) or only the reperfusion period (C ). Specific groups in the scatterplot are identified in the symbol legend, with open symbols used for relatively hypoglycemic groups and closed symbols for relatively hyperglycemic groups. For each plot there was a significant negative correlation between the paw withdrawal thresholds and the mean glucose level (mM) during ischemia/reperfusion injury for CPIP rats (R2= coefficient of determination). dex = dextrose; ins = insulin; NS = normal saline; PWT = paw withdrawal threshold.
