Figure 1

Receiver operating characteristic curve for predicting diabetes after 3 years using baseline blood glucose and HbA1c values. The areas under the ROC curve for FPG, 2hPG, and HbA1c were 0.752 (95% confidence interval 0.718–0.787), 0.710 (95% confidence interval 0.671–0.748), and 0.756 (95% confidence interval 0.720–0.793), respectively.
