The Longer, the Better: Continuous Glucose Monitoring Use for ≥90% Is Superior to 70%–89% in Achieving Tighter Glycemic Outcomes in Children with Type 1 Diabetes
Authors' conclusion
CGM use for ≥90% is associated with tighter glycemic control compared with 70%-89% use.

Main finding
As reported in the abstract
HbA1c · 2023
HbA1c % ≥90% 6.8% · 70-89% 7.4%
- ≥90% vs 70-89%: P < 0.001 — lower with ≥90%
Observational data: associations, not effects.
