Design outcomes

Primary

Measure	Time frame
Outcome Measurements Daily glucose fluctuations by using a continuous glucose monitoring system (Freestyle Libre Pro, Abbot Diabetes Care Inc., USA, Japanese pharmaceutical approval: 22800BZX00227000). Glucose profiles are consistently measured during the 14-day test period. Measurement outcomes Basic glucose response: (a)Effective glucose peak value (Gp) from glucose baseline (b)net MAGE (mean amplitude of glucose excursion) Definition of Net MAGE MAGE was defined as the average of upward (MAGE(+)) and downward (MAGE(-)) excursions exceeding the standard deviation of glycemic excursion data over a day measured by CGM as follows: MAGE=(MAGE(+) + MAGE(-))/2 Glycemic excursion fluctuations can be evaluated by the upper and lower envelopes of excursion profiles. Net glycemic fluctuation amplitudes (net MAGE) defined for each glycemic peak as abs[G(i)-GN(i)], where G(i) and GN(i) are glucose peak and baseline value of the ith peak of the daily glucose excursion profile.	—
