Comparison of glycemic parameters and HbA1c between the low-frequency group and high-frequency group. Data are percentages except for sample size of group (n) and for mean glucose. Glycemic parameters are presented in mg/dL. Optimal glycemic control is defined as time in range > 70% and time below range < 70 mg/dL) < 4%. The group with more frequent scanning had better time above range, mean glucose, a coefficient of variation range than the group with less scanning
