From: Predicting hypoglycemia after treatment of hyperkalemia with insulin and glucose (Glu-K60 score)
Calibration plot of the predictive score. Observed risk (red circle) versus predicted risk score (solid blue line) of posttreatment blood glucose ≤ 70 mg/dL (≤ 3.9 mmol/L). The more circles near the solid blue line indicated the more accuracy in predicting the risk score of posttreatment blood glucose, and this figure showed acceptable accuracy. The size of the circle represented the frequency of posttreatment blood glucose in each total score
