Yeah, they didn't provide them -- you can calc the raw ratios but not the rates -- but these are proportional hazard models and the amazing feature of them is that you don't need to know the underlying rates in order to get the relative risk ratios. David Cox was a pretty smart guy. He passed a year or so ago, just short of his 100th birthday. Probably didn't do IF.
