Effect of Early Glycemic Control in Youth-Onset Type 2 Diabetes on Longer-Term Glycemic Control and β-Cell Function: Results From the TODAY Study

Diabetes CarePublished Secondary analysis of the TODAY randomised trial

Authors' conclusion

Early tight glycemic control in the TODAY study was related to β-cell reserve and translated to better long-term glycemic control. However, tight early glycemic control on the randomized treatment in the TODAY study did not prevent deterioration of β-cell function.
