Outcome Measures

Primary Outcomes (1)

  • Comparison of glycemic control obtained under closed loop according to the system used: SG versus CIQ

    Time spent in target range (between 70 and 180 mg/dL) after 12 months following initiation of the closed-loop system, as measured by continuous glucose monitoring (CGM).system, as measured by continuous glucose monitoring (CGM).
