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.
Diabetic Mediterranean Diet 
This article’s use of relative risk masks the parlous state of diabetes care today and misrepresents a catastrophe as a triumph. It points out the burden of diabetes is rising in spite of the improvements because of increasing incidence, yet they offer no explanation or remedy. Lipstick on the pig …
From Figure 1, I see that in 2010, kidney death, amputation, stroke and heart attacks were about 25, 35, 50 and 60 respectively per 10,000 diabetics, but only 2, 3, 6 and 8 per 10,000 non-diabetics. So in 2010, diabetics had 12 times the kidney death, 12 times the amputations, eight times as many strokes and seven times the MIs of non-diabetics.
Yes, the numbers are better than they were in 1995, but I wonder if if this appalling carnage was and is actually due to the prescribed high-carbohydrate diet plus the drugs that it renders necessary. Moreover, I wonder how much of the improvement since 1995 is because so many of us have realized this prescription is a death sentence.
I’m a thirty-year insulin-dependent diabetic on Dr Bernstein’s low carbohydrate diet and no drugs save for insulin. My HbA1c is 5% and my EBCT coronary artery calcium score is zero – like a non-diabetic free of heart disease. I didn’t hear of Dr Bernstein’s diet from my doctor when my HbA1c was 8% on the diet he prescribed, but rather from Amazon.com. Lucky for me I did, since I’d likely be among those statistics by now if I hadn’t changed my diet.
Hi, Jonathan.
It’s a crying shame that more people don’t know about Dr. Bernstein’s diet and other very-low-carb diets for diabetes.
Congratulations on your excellent results!
