  1. aThe two-phase and linear models are fitted to subsets of the 0 – 20 mSv liver data with latency φ = 36.90 years (optimal for the two-phase model on the 0 – 20 mSv data, see Table 3)
  2. bRi is the excluded dose range (in 10 mSv units). Si consists of those cells in the 0 – 20 mSv subcohort whose weighted adjusted colon dose does not fall in Ri
  3. cPerson-years in Si
  4. dCases (liver cancer deaths) in Si
  5. eLRT = LRT2p-lin for comparing the two-phase model with the linear model when fitted to Si with latency φ = 36.90 years
  6. fERR1 is the estimated Excess Relative Risk at 10 mSv when the two-phase model with latency φ = 36.90 years is fitted to Si
