Developmental phase	Not applicable

Assessment
Primary outcomes	Glycemic control is estimated as the mean blood glucose (MBG), the area under the glucose curve above 10.0mmol/L (area under the curve [AUC]>10), and the percentage of time above 10.0mmol/L (t>10).The AUC is calculated using the trapezoidal method. Intraday glycemic variability is assessed as the standard deviation (SD) and the mean amplitude of glycemic excursions (MAGE). Day-to-day glycemic variability is assessed as the mean of daily difference (MODD). Hypoglycemia, which is defined as a sensor value of <3.9mmol/L, was also calculated as a total time at <3.9mmol/L. Severe hypoglycemia is defined as a sensor value of <2.8mmol/L.
