The concept of maintaining blood glucose levels within the 70-180 mg/dL range, known as time-in-range, has raised questions regarding its representation true physiological euglycemia. Some have speculated that focusing on time spent 70-140 introduced in tight range (TITR) through International Consensus statement, could serve a more precise metric for assessing normoglycemia individuals with type 1 diabetes. This article delves into current status TITR an emerging marker and explores how...
