Thanks for the summary, I just read the article and I feel like you touched the main points. Regarding survival, I also noticed it, surprising. Could you define "survival rate" for someone who's not in the field? Does it mean what it looks like it means, i.e., survival rate is higher when rats die at an older age in average?

Not a medic or biologist (or a statistician!) so I don't know the specific definition, but I assumed it simply means the number of rats still alive at the end of the 106 week period.

  This is correct. Because you can't know the future, 'survival' means up to a certain point (whenever you stop looking), beyond which adverse events are not counted (even if you know they happened).
