Research progress on time in glucose target range as an indicator of blood glucose management

In the management of patients with diabetes mellitus, blood glucose monitoring is the basis for understanding blood glucose control. The blood glucose level is the key to evaluating individual response and safety of treatment. Blood glucose monitoring technology is constantly developing, and the indicators used to evaluate blood glucose management are becoming more diverse. The time in the glucose target range （time-in-range, TIR）, as an emerging evaluation index for blood glucose, has attracted widespread attention since it can provide clinicians and patients with more insights on blood glucose management. At present, the correlation between TIR, and diabetes mellitus-induced complications and other blood glucose management indicators has been extensively studied. Therefore, research progress on the TIR as a blood evaluation indicator was reviewed in this article.
