FIG. 1.
ADRR distribution by each study visit is shown for exenatide and insulin glargine over the course of study. Overall, ADRR was lower for exenatide-treated patients (P = 0.001). A 2 × 6 analysis of variance of ADRR per study visit after the first visit shows that variability is reduced shortly after the initiation of treatment in both groups (F = 112.5, P < 0.001), and reduction of variability is slightly more pronounced for exenatide-treated patients compared with glargine-treated patients (treatment × visit effect, F = 7.1, P < 0.0001). Data are mean ± SE values.
