Achieving at Least 15% Weight Loss Within 2 Years of Type 2 Diabetes Diagnosis Is Associated With Lower Risks of Macrovascular and Microvascular Complications: A U.K. Cohort Study
Main finding · First macrovascular eventResult — go to the resultHazard ratio 0.86 95% CI 0.81–0.91Authors' conclusion
Achieving ≥15% weight loss early in type 2 diabetes was associated with clinically meaningful lower risks for macro- and microvascular complications and better glycemic control compared with stable weight.
