  • Data are adjusted P value with OR (95% CI)* and adjusted P value with hazard ratio (95% CI)†. The case/control sample is composed of 895 Pima subjects, 300 case subjects with diabetes onset age <25 years, 334 nondiabetic control subjects age >45 years, and 261 additional sibs of either case or control group for within-family test. The population-based sample consists of 3,501 full-heritage Pima Indians and 1,561 diabetic and 1,940 nondiabetic subjects at the last visit. Most of the case/control subjects (n = 715) were included in the population-based sample.

  • *

    * In the case/control analysis, a logistic regression was used to adjust for sex, birth year, and family membership.

  • For the population based-sample, a survival analysis (Poisson model) was applied to adjust for sex, birth year, age of last visit, age of onset for diabetes, and family membership. All P values are for a recessive genetic model.
