Figure 3 Receiver operator characteristics (ROC) curve and AUC of ROC curve. Comparison of the ROC curve of the sucrose test and AUC at each time point. There was no significant difference between the urine collection method and the serum method from 30 to 300 min. AUC: Area under the ROC curve; SE: standard error; CI: confidence interval.
