%cvw, percentage coefficient of variation; CI, confidence interval; CONGA, continuous overlapping net glycemic action, with “n” indicating the number of hours; CV, coefficient of variation ([SD/mean]×100); MAGE, mean amplitude of glycemic excursions, with MAGEc, MAGEave, and MAGEabs.gos being MAGE that exceeded 1 SD in a single direction, MAGE calculated from both upward and downward glycemic excursions, and MAGE by the group of signs method, respectively; SDw, glucose SD within each 22-h CGMS measurement; t>10.0 mmol/L, time spent in hyperglycemia.
