EDIC: Metabolic Memory — Early Intensive Therapy Reduces Cardiovascular Events by 42–57% Over 17 Years in Type 1 Diabetes

The EDIC study demonstrated that 6.5 years of intensive glycaemic therapy during the DCCT reduced cardiovascular events by 42–57% over 17 years of follow-up despite subsequent HbA1c convergence between groups, establishing the concept of metabolic memory and providing foundational evidence that early intensive glycaemic control produces durable cardiovascular protection extending decades beyond the intervention period.

DCCT: Intensive Insulin Therapy Reduces Microvascular Complications by 39–76% in Type 1 Diabetes

The Diabetes Control and Complications Trial demonstrated that intensive insulin therapy targeting near-normal blood glucose reduced the risk of developing retinopathy by 76% in primary prevention and slowed progression by 54% in secondary intervention, while also substantially reducing nephropathy and neuropathy, establishing the foundational evidence for tight glycaemic control in type 1 diabetes.

Does Metformin Improve Insulin Resistance in Type 1 Diabetes?

A clamp-based RCT finds metformin does not reduce hepatic insulin resistance in type 1 diabetes, arguing against its use as an insulin-sensitiser. PICO summary and commentary.

Can Online Education Reduce Stigma and Improve Body Image in Adults with Type 1 Diabetes?

A randomised trial finds a brief four-session online programme reduces diabetes stigma and improves body image and coping in adults with type 1 diabetes, sustained at follow-up. PICO summary and commentary.

Is Automated Insulin Delivery Better Than Daily Injections for Type 1 Diabetes?

A large international RCT finds automated insulin delivery (MiniMed 670G/770G) improves HbA1c in those above 8% and reduces hypoglycaemia in those at target versus multiple daily injections in type 1 diabetes. PICO summary and commentary.

Low-Carb vs Mediterranean Diet and Bone Turnover Markers in Young Type 1 Diabetes: A Null Result

A 24-week RCT finds neither a low-carbohydrate nor a Mediterranean diet significantly changes bone turnover markers in young people with type 1 diabetes, an exploratory null result. PICO summary and commentary.
