ESRRA and leukemia: The fact that for the stomach, liver, lung, and leukaemia rather similar results for ERR1 and latency are obtained from fitting the two-phase model across the 5 - 500 mSv dose range as from fitting across the 0 - 20 mSv dose range suggests that there is also sufficient information in the 0 - 20 mSv data to justify fitting this model.
