Legend of Table S2:

Six multiple logistic analyses against each C-peptide immunoreactivity (CPR) index together with duration of diabetes, BMI, andHbA1c in common are shown. Six CPR indices were separately analyzed in order to avoid multicollinearities lying between CPR indices.

ΔCPR, increment of CPR during glucagon test; CI, confidence interval; CPI, C-peptide index; CPI2h, CPI 2 h after breakfast;CPR2h, CPR 2 h after breakfast; FCPR fasting CPR; n.s., not significant; SUIT, secretory unit of islets in transplantation.
