Increased Hemoglobin A1c Time in Range Reduces Adverse Health Outcomes in Older Adults With Diabetes

Retrospective observational study (n=402,043, US) found over an average of 5.5 years of follow-up, lower HbA1c time in range (TIR) was linked to increased mortality (0 to <20%: HR 1.22; 95% CI 1.20–1.25) and CVD (0 to <20%: 1.14; 1.11–1.19) vs. HbA1c TIR 80–100%.
