"It stresses the importance of getting and maintaining glycemic control early in the disease, while also noting that there is a benefit (albeit much weaker) with delayed glucose control," said Gerstein, a professor of medicine at McMaster University in Hamilton, Canada. The current analysis differs from the Veterans Affairs Diabetes Trial (VADT) — which showed that glucose control soon after diagnosis had cardiovascular benefits 10 years later but not 15 years later — in that it is based on a model, not actual events, he noted.
