Overall group comparisons of the metabolic parameters at month 3 showed significant differences between the vildagliptin and placebo group for 2HPG (p¼0.034; Figure 3B), and HbA1c (p¼0.039; Figure 3C), but not for FPG (p¼0.249; Figure 3A). HbA1c was still significantly differ- ent between the vildagliptin and placebo group at month 4 (p¼0.025; Figure 3C). Overall group differences (not the individual changes) from baseline to month 3, respectively month 4, are depicted in Table S1.
To gain further mechanistic insights, a subset of patients underwent fsOGTT at baseline and at months 3 and 4.
