Publications from the Carcinogenic Potency Database Project. This result is expected because carcinogenic potency values are constrained to a narrow range about the maximum dose tested in a bioassay, and the maximum doses administered to rats and mice are highly correlated and similar in dose level.
Results are similar for the pair male rats and male mice.
Using a strength of evidence approach, weaker carcinogens are somewhat less likely than stronger carcinogens to be identified by 2 sex-species groups.
