  • Characteristics of 2,530 Pima subjects divided by glucose tolerance at baseline examination. Data are means ± SE, with the exception of gamma globulin (geometric mean and range of ± 1 SE). ANOVA was in keeping with significant differences among groups for all variables (age, BMI, 2-h glucose, gamma globulin; P < 0.0001) after adjustment for gender.
