(a) Number of tumor-bearing animals / number of animals examined at site.
(b) Poly-3 adjusted lifetime tumor incidence.
(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.
Logistic regression is an alternative
method for analyzing the incidence of non-fatal tumors. The Cochran-Armitage
and Fishers 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
# Tumor rates based on number of animals necropsied.
