Animals that died in advance of 6 months were not examined, along with the survival periods weren't reported. Animals ended up killed when noticeable tumours had been noticed or if they were moribund; all survivors were killed at two a long time.

Furthermore, the absence of the Affiliation isn't going to always suggest the absence of a causal relationship.
