News — The study found that the average A1C in the CGM group fell 0.4%, from 8.9% at the time the trial began to 8.5% at six months; whereas for people in the control group, their average A1C remained unchanged at 8.9% over the six-month study period. This substantial and significant improvement in glycemic control is one of very few interventions that have demonstrated a positive impact in this challenging age group. Researchers also found:
- Nearly twice as many people in the CGM group, as those in the standard test strip group, had a reduction in A1C of 0.5% or more at six months (44% versus 25%).
- CGM users were four times more likely than non-users to lower their A1C by one point or more (25% versus 6%).
- Very high or very low blood glucose episodes can be dangerous, especially overnight when people are generally not monitoring their glucose levels. Regular CGM use increased the amount of time in target range (glucose levels of 70 mg/dL to 180 mg/dL) by almost two hours throughout the day.
