  1. Data are mean ± SD (range).
  2. HbA1c, hemoglobin A1c concentration; CGM, continuous glucose monitoring; MBG, mean blood glucose concentration; SD, standard deviation; BG, blood glucose concentration; WW method, 120-day glycemia was extrapolated based on two daily profiles for working days and for weekend obtained using the point-wise averaging; ID method, 120-day glycemia was extrapolated based on the glucose data with no averaging.
