Male interim sacrifices(days): 456 Female interim sacrifices(days): 457 (d) Observed incidence at terminal kill. (f) Beneath the control incidence are the P-values associated with the trend test. Beneath the dosed group incidence are the P-values corresponding to pairwise comparisons between the controls and that dosed group. The life table analysis regards tumors in animals dying prior to terminal kill as being (directly or indirectly) the cause of death. The incidental tumor test regards these lesions as non-fatal. Logistic regression is an alternative method for analyzing the incidence of non-fatal tumors. The Cochran-Armitage and Fisher's exact tests compare directly the overall incidence rates. For all tests, a negative trend is indicated by "N". (e) Value of Statistic cannot be computed.
