a
The subcohort is an approximate 1% random sample of all participants in the Eight Series Study for which comprehensive dose reconstruction was performed [17]. The full cohort is everyone in the Eight Series Study with a NuTRIS dose, adjusted to be comparable with the subcohort dose.
b
Adjusted for service, rank (enlisted/officer), year of birth and year of first participation at a weapons test (and sampling fraction for the case-cohort analyses).
