*Significantly higher (p†Significantly higher (p‡Significantly higher (pThe incidence and multiplicity of lung tumor formation in female A/J mice treated with low-dose NNK [NNK(L)], high-dose NNK [NNK(H)], TCDD, and TCDD combined with NNK(L). Tumor incidence is provided as the number of animals with tumors divided by the total number of animals at risk (%). Tumor multiplicity is the average tumor number observed in tumor-bearing mice. The data for lung tumor multiplicity are given as the mean ± SEM. *significantly higher (p†significantly higher (p‡significantly higher (p
