Wentholt IM, Hoekstra JB, DeVries JH: A critical appraisal of the continuous glucose–error grid analysis: response to Clarke et al. (Letter). Diabetes Care 30:450–451, 2007

In the second paragraph of the above-listed letter, “n = 250” was inadvertently changed to “250 mg/dl.” The correct sentence is as follows: “This level of significance implies that degrees of freedom were derived from all data pairs in the hypoglycemic range (n = 250) rather than from the actual amount of participants (n = 16).”
