RCT: Among patients with Type 2 diabetes treated with basal insulin with poor glycemic control (mean baseline HbA1c level = 9.1%), continuous glucose monitoring reduced HbA1c level by 0.4% compared to usual care (8.0% and 8.4%). Patient engagement (i.e., adherence, diet, physical activity in response to CGM readings) was the most likely source of improved glycemic control.
