*HRs and 95% CIs derived from Cox models using age as the time scale, stratified on birth cohort (<1950, 1950–1959, 1960–1969, 1970+) and adjusted for gender (minimally adjusted).
†Fully adjusted models additionally included total years worked as a radiologic technologist in different time periods (<1950, 1950–1959, 1960–1969, 1970+), reported work with brachytherapy and other radionuclide procedures, smoking status (never, former, current), number of alcoholic drinks consumed per week (0, 1–6, 7–13, 14+), and body mass index (<18.5, 18.5–24.9, 25.0–29.9, 30.0–34.9, ≥35).
