Characteristics associated with having a hemoglobin A1c ≤ 7 % (≤53 mmol/mol) among adults with type 1 diabetes using an automated insulin delivery system
Authors' conclusion
Our study indicates that among AID users, in order to maximize benefits, additional support is needed for those who do not have a bachelor's degree and/or who have been using an insulin pump for a long time.
Study context

As reported in the abstract
Reporting an HbA1c ≤ 7 % when using an AID
Odds ratio (95 % CI)P value
