Poisson and Cox regressions were used to investigate dose-response relationships. In all analyses, TCDD and TEQ exposures were related to total cancer mortality. Investigations on latency did not show strong effects. Different methods were applied to investigate the robustness of the results and yielded almost identical results. The results were used for unit risk estimation.
Uncertainties regarding the dose-response function remain.
We thank S. Holzmeier for efficient help with the analysis and one referee for an extensive and constructive review.
