MedPageToday has the details. This jibes with my experience over the last 30 years. A quote:
An analysis of national data found that rates of myocardial infarction (MI) in diabetic patients dropped about 68%, and amputation rates were halved between 1990 and 2010, Edward Gregg, PhD, of the CDC in Atlanta, and colleagues reported in the April 17 issue of the New England Journal of Medicine.
Strokes and deaths from hyperglycemic crisis also fell dramatically.
The number of adults reporting a diagnosis of diabetes more than tripled during the study period.
