Fig. 2: Fasting and AUC c-peptide in study groups over time.

Fasting c-peptide (a) was measured in the three study groups (GABA-red, GABA/GAD-blue, and placebo-black) at baseline (Time = 0,prior any treatment) and at 1, 5 and 12-months thereafter. AUC c-peptide (b) was calculated over time in the three study groups. Results are given as mean ± 95% CI. No statistical differences were noted by two-sided analysis of covariance (complete statistical data is summarized in Supplementary Table 1). Source data are provided as a Source Data file.
