The subtleness if the differences between the groups seems to undermine their hypothesis. How are they saying this is statistically significant?

- tim333 10y agoI'm not sure. Also from an NYT article: >Also it was unusual that the control group had zero tumors. In previous studies at the National Toxicology Program, an average of 2 percent of rats in control groups developed gliomas. Had that happened in this study, there would have been virtually no difference between the exposed rats and the controls.
