Here is a list of all the AHRQ publications
Among the summary guides, a couple of the best are the Guide to Premixed Insulin for Type 2 Diabetes and the Guide to Pills for Type 2 Diabetes. They're a lot like Consumer Reports for diabetes meds, right down to the grid charts with the check marks. Both guides start with the basics, even including directions on how to pronounce hypoglycemia, but they're also remarkably thorough. The pill guide compares every pill, from its good effects to its side effects, and concludes with detailed pricing comparisons. The premixed insulin guide also starts with the basics and is equally comprehensive, starting with a diabetes primer and again ending with price comparisons. If you are at all confused about diabetes pills or premixed insulin, take a look at these guides. After reading them, you won't be confused any longer.
