  1. a Geometric mean presented for those variables natural log-transformed.
  2. bAdjusted odds ratio controls for age, BMI group, and total lipids (except in the case of lipid-adjusted PCBs which does not control for lipids).
  3. cA total of 7 men had diagnosed diabetes and 56 men were without a diagnosis of diabetes.
  4. dVariable not normally distributed, therefore natural log-transformed variable used in logistic regression model.
  5. ePCB is a sum of all PCB congeners measured, <LOD = zero; Dioxin-like PCBs include 105, 118, 156, 157, 167, 189; Non dioxin-like PCBs: sum of all other PCBs beside dioxin-like; Estrogenic PCBs: sum of 52, 99, 101, 110, 153; Anti-estrogenic PCBs: sum of 105, 156.
