Table 6. Number of cases (N) and excess relative risks (ERRs) of primary tumours of the CNS, leukaemia, and lymphoma related to cumulative organ doses in mGy, adjusted for the presence of PFs for specific cancers, for exclusion periods of 1, 2, 3, and 4 years.

ERRs are estimated by Poisson models (maximum likelihood estimates) adjusted for gender, period of birth (1995–2001, 2002–2010), attained age (in years), time since entry into the cohort (in years), and the presence of PF (yes/no).
