↵2-150 Excludes women and eight men who had missing TCDD concentrations.
↵2-151 One non-exposed subject in the original analysis was found to actually have been exposed, leading to 990 exposed in the present analysis v 989 in the original publication (Henriksen et al 19972).
↵2-152 Calculated only for those with >10 ppt.
↵2-153 The limit of detection varied by sample volume of blood available; the median was 3 ppt.
