(a) Number of tumor-bearing animals / number of animals examined at site.
(b) Kaplan-Meier estimated lifetime tumor incidence after adjustment for
intercurrent mortality.
(c) Observed incidence at interim kill.
Male interim sacrifices(days):
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.
(I) Interim sacrifice
(T) Terminal sacrifice
