Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Blinded continuous glucose monitoring
The blinded CGM group will be using the Medtronic iPro2 system (Enlite sensor + iPro2 transmitter).
Continuous glucose monitoring
The blinded CGM group will be using the Medtronic iPro2 system (Enlite sensor + iPro2 transmitter). The real-time CGM group will be using the 530g system (inactivated 530g insulin pump (no insulin used, only used as display for CGM), Enlite sensor, MiniLink transmitter)
Real time continuous glucose monitoring
The real-time CGM group will be using the 530g system (inactivated 530g insulin pump (no insulin used, only used as display for CGM), Enlite sensor, MiniLink transmitter)
