  1. Values are expressed as means ± SD. 1, years at the beginning of the study. 2, Number of subjects who significantly decreased mean pre-meal diary BG. 3, Mean pre-meal of diary blood glucose, mg/dL, LBG = lower than 81.8 mg/dL. HBG = higher than 81.8 mg/dL 4, Number of subjects who fell into the LBG at end of the study. 5, grams/d. Asterisks indicate significant differences (Student's t-test or Yates test): *, P < 0.05; **, P < 0.01; ***, P < 0.001 vs. respective control group values based on "post - pre" measurements (a), or vs. baseline values of the same group (b).
