Data displayed as mean ± SD. Abbreviations: TAR, time above range (level 1 181–250 mg/dL, level 2 > 250 mg/dL); TIR, time in range (70–180 mg/dL); TBR, time below range (level 1 : 54–69 mg/dL, level 2 < 54 mg/dL); SD, standard deviation; CV, coefficient of variation. †Values is weighted for the number of readings/hour.
