Fig 1. Receiver operating characteristic curve for HbA1c to discriminate subjects with pre-diabetes.

Fig 1

The figure shows an ROC curve for HbA1c (continuous) to discriminate subjects with pre-diabetes (impaired FPG ≥5.6 mmol/l). The area under the curve value was AUC: 0.668, (95% CI: 0.627–0.710).
