This is the full paper http://dst.sagepub.com/content/early/2014/10/10/1932296814554415.abstract – a Letter to the Editor was already mentioned.

The paper suggests that a different glucose error grid is needed for diabetes complications such as diabetic retinopathy rather than the traditional glucose error grid which deals with acute injuries. This is because slightly or even moderately elevated glucose would fall in the no treatment needed zone of a traditional glucose error grid but would be harmful for diabetic complications. Thus, a glucose meter could look good in terms of a traditional glucose error grid but have a bias that would allow elevated glucose to occur for up to 6 months – until the patient’s next A1c determination. Patients and providers would be better informed if they knew which glucose meters were free from these long-term biases.
