Impact of Continuous Glucose Monitoring on Clinical Outcomes and Productivity Losses Among People Living With Type 2 Diabetes Not Using Insulin From an Employer’s Perspective
Main finding · Mean HbA1c, overallResult — go to the resultMean reduction 0.52 %Authors' conclusion
In this population, CGM was associated with improvements in clinical outcomes and absenteeism, although the economic implications require further evaluation. BMI and absenteeism were statistically significantly improved among persistent patients, compared with those of the nonpersistent cohort. Employers could benefit from broader coverage of CGM in this population.

- Persistentn = 33
- Outcome
- Mean HbA1c, overall
- Follow-up
- 360 days after vs 360 days before CGM initiation

Main finding
As reported in the abstract
Mean reduction
0.52 %
P = 0.042
- Mean HbA1c before → after CGM initiation
- 7.6% to 7.1%
Observational data: associations, not effects.
