Data presented in mean ± standard deviation, proportion or median (IQR) and analyzed by Student's t-test, Mann–Whitney test (duration of CGM usage) or Chi-square (gender, insulin regimen). Boldface indicates statistical significance.

CGM, continuous glucose monitoring; COV, coefficient of variation; HbA1c, hemoglobulin A1C; IAH, impaired awareness of hypoglycemia; IQR, interquartile range; MDI, multiple daily injections; NA, normal awareness.
