2. Study Objectives
The benefits of real-time continuous glucose monitoring (CGM) have been demonstrated in patients with type 1 diabetes
Aim was to compare the effect of two modes of use of CGM, patient-led or physician-driven, in subjects with poorly controlled type 1 diabetes

3. Study Design
197 patients with type 1 diabetes aged 8–60 years with HbA1c > 8% randomly assigned to:
Patient-led CGM
Physician-driven CGM
Conventional self-monitoring of blood glucose
Glucose control outcomes assessed at 1 year

4. One-year CGM in type 1 diabetic patients
Table 1- Characteristics of patients with type 1 diabetes screened for inclusion in the study
Data are mean 6 SD unless otherwise indicated. †P , 0.05 for comparison between FAS groups. ‡P , 0.05 for comparison between FAS population and screenfailure
population. xPatients with $1 episodes of severe hypoglycemia during previous year. A severe episode of hypoglycemia was defined as an event requiring
assistance from another person

5. Figure 1- HbA1c change from baseline (M0) at 3, 6, 9, and 12 months in groups 1, 2, and 3. Values are means (95% CIs). The data correspond well to the estimated mean and CI of the model. *P , 0.05 for comparisons between the two experimental groups and the control group at each time point. M, month.

*All adjusted using the Hochberg procedure. xSD of 8-point daily blood glucose profile (mg/dL), values aremeans (95%CIs). {A severe episode of hypoglycemia was
defined as an event requiring assistance from another person to administer carbohydrate/glucagon.

7. Conclusions
Both patient-led and physician-driven CGM provide similar long-term improvement in glucose control in patients with poorly controlled type 1 diabetes
Physician-driven CGM mode used fewer sensors.
