Table 2. Hemoglobin A1c values of the four glycemic state groups.

NGT INDET IFG IGT
HbA1c, mean 5.6 5.6 5.5 5.5
HbA1c, SD 0.46 0.50 0.41 0.45
n 34 6 7 9
P-value 0.987 0.690 0.874

P-values are compared to the normal glucose tolerance group (Student’s t-test).

HbA1c, hemoglobin A1c; INDET, indeterminate glycemia; IFG, impaired fasting glucose; IGT, impaired glucose tolerance; NGT, normal glucose tolerance; SD, standard deviation.
