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. (g) Poly-3 adjusted lifetime tumor incidence. (I) Interim sacrifice (T) Terminal sacrifice # Tumor rates based on number of animals necropsied. * To the right of any statistical result, indicates significance at (P<=0.05). ** To the right of any statistical result, indicates significance at (P<=0.01).
