Exploring the interaction between ethnicity, deprivation and the use of continuous glucose monitoring (CGM) on diabetes outcomes—A study from the Association of British Clinical Diabetologists

Diabetes Obes MetabPublished Retrospective cohort study

Authors' conclusion

Ethnicity and deprivation independently influence glycaemic control. However, CGM yields equitable HbA1c improvements across all subgroups.

Further findings

HbA1c reduction with CGM · follow-up

Significant HbA1c reductions across all Index of Multiple Deprivation (IMD) groups; most notable in very high deprivation areas (p < 0.001)
−8.54%
Reduction similar across ethnicities (all p = 1.0)
