Residual β-Cell Function in Type 1 Diabetes Followed for 2 Years after 3C Study

Figure 3

Stimulated C-peptide by duration and age at diagnosis. The associations of age at diagnosis and diabetes duration with stimulated C-peptide were illustrated in (a). Each box represents the mean stimulated C-peptide of the individuals under the corresponding condition of diabetes duration and age of diagnosis. The associations of age at diagnosis and diabetes duration with decline of stimulated C-peptide (v8-v0) were shown in (b). Each box represents the mean decline of stimulated C-peptide (v8-v0) under the corresponding condition of diabetes duration and age of diagnosis. V0: the 0th visit; V8: the 8th visit.
