Figure 2

Receiver operating curve analysis of fasting C peptide in differentiating beta cell function in autoimmune diabetes. The differentiating diagnostic value of fasting C peptide (FCP) in autoimmune diabetes was shown in the receiver operating curve (ROC). The top left corner of the curve represented the optimal FCP cur-off point, which was at the level of 300 pmol/L.
