Tschritter O, Fritsche A, Shirkavand F, Machicao F, Häring H, Stumvoll M: Assessing the shape of the glucose curve during an oral glucose tolerance test. Diabetes Care 26:1026–1033, 2003

In the above-listed article, on p. 1027, under the head “Definition of monophasic and biphasic plasma glucose curve shapes,” the sixth sentence should read: “The shape index, calculated as glucose at 120 min (Gluc120) minus glucose at 90 min (Gluc90) was treated as a continuous variable in the correlational analyses” [i.e., “120 min (Gluc120)” and “90 min (Gluc90)” were transposed]. In the legend of Fig. 1, the fourth sentence should read: “The shape index was calculated as Gluc120 − Gluc90” (i.e., “Gluc120” and “Gluc90” were transposed).
