  1. The FGM data used seven consecutive days, and the values in the table represent the average of 7 days
  2. Data are results of Spearman rank correlation. Correlation is significant at P < 0.05*
  3. SD: standard deviation; CV: coefficient of variation; GMI: glucose management indicator; TBR: time below range (< 70 mg/dl); TIR: time in range (70–180 mg/dL); TAR: time above range (> 180 mg/dL); MODD: mean of daily difference of blood glucose; LBGI: low blood glucose index; HBGI: high blood glucose index
