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 other POP groups. Model 2–results are adjusted for the other POP groups as well as age, gender, BMI, serum concentrations of total lipids. Wald χ2 p-value is for a test of differences in proportions of diabetes across the full set of quartiles. | |||||
