Early Continuous Glucose Monitor Use in Children and Adolescents With Type 1 Diabetes: Rates of Initiation and Impact on Glycemic Outcomes
Authors' conclusion
In summary, early initiation of CGM within the first 6 months of diagnosis is associated with improved HbA1c outcomes at 3 years postdiagnosis.

- Participants
- 4,164 children
- Exposure
- Timing of continuous glucose monitor (CGM) initiation after T1D diagnosis and non-CGM use
- Outcome
- HbA1c
- Follow-up
- 3 years postdiagnosis
