Association between frequency of self-monitoring of blood glucose and glycemic control in patients with type 2 diabetes
Authors' conclusion
Frequent SMBG was associated with better glycemic control in non-insulin-treated patients. Insulin-treated patients with poor glycemic control may benefit from frequent SMBG.
