I would like to make two points, however. First, Barr and colleagues misinterpret the data in their Figure 2. The graph relates the prevalence of retinopathy to glycemic indices broken down into deciles. Each point represents the average prevalence of retinopathy in the decile but the lowest glycemic value of that decile. Barr and colleagues state that the proportion of persons with retinopathy begins to ...References1. Barr RG, Nathan DM, Meigs JB, Singer DE.
