Changes in HBA1c and fasting blood glucose levels. A The reduction in HbA1c levels in the control (grey bars) and the active group (black bar) after 6–12 months of follow up. Least squares mean difference between the active and the control group 0.53 (0.31-0.76)%, p < 0.001. B The reduction in fasting blood glucose levels (FBG) in the control (grey bars) and the active group (black bar) after 6–12 months of follow up. Least squares mean difference between the active and the control group 27.85 (15.74-39.95) mg/dl, p < 0.001.
