Note: The number (N) of subjects in each quartile is given and the number of subjects with diabetes is given in parentheses. Model 1–results are adjusted for age, gender, BMI, and serum concentrations of total lipids, but not for total PCBs. Model 2–results are adjusted total PCBs as well as age, gender, BMI, serum concentrations of total lipids. Wald χ2 p-value is the significance level of the differences in proportions of diabetes across the full set of quartiles. | |||||
