Statistically Analyzed DTT Pathology Lesions (with Incidence)

This dataset contains lesions found in studies where each dose group had two or more of the lesion.  Lesions with a statistically significant difference (p<0.05) in incidence between the exposed and control animals are flagged.

The data contained herein were collected in 2020 from a source now known to contain omissions.  We plan to replace with an up to date dataset in 2023.
