The pooled analysis of the 18 month studies is highly significant ( p = 0.005) but not significant for the 24 month studies ( p = 0.686).

Additional file 2 : Tables S1–S13 provide the tumor count data for all tumors with a significant trend test ( p ≤ 0.05) in at least one study of the same sex/species/strain along with the doses used (mg/kg/day) and the number of animals examined microscopically in each group.
Malignant lymphomas are significant in studies C ( p = 0.016) and D ( p = 0.007) and marginally significant in study B ( p = 0.087) in male mice.
The net effect of requiring monotonic dose-response is a severe reduction in the ability to detect a positive trend and a large increase in the probability of a false negative finding.
