Impact of transitioning from conventional blood glucose monitoring to continuous glucose monitoring on glycemic control and self-management in adults with type 2 diabetes on oral glucose-lowering medications
Authors' conclusion
Switching from conventional SMBG to CGM significantly improved glycemic control and self-management in PwT2D treated with oral ADMs. This observation highlights the potential for broader integration of CGM into this population.
Study context
