Figure 2

Scatter graph demonstrating the relationship between the GCS scores and the plasma glucose levels. Closed circles indicate the patients who had recurrent hypoglycemic episodes. Open circles indicate the patients who had no hypoglycemic episodes. Open triangles indicate the patients whose hypoglycemic episodes were unclear. (a) The value of the Spearman's rank sum test was statistically high (ρ = 0.458) in the diabetic patients. (b) The value of the Spearman's rank sum test was high (ρ = 0.627) in the non-diabetic patients, but not significant.
