Results are based on demographic data presented for 1080 subjects who completed the baseline questionnaire, excluding two with unknown date of death.
O indicates observed; RR, rate ratio (based on Poisson regression); analyses are adjusted for sex and RT exposure.
Treatment data were available for 921 subjects, including 73 of 87 deaths. RT, radiation therapy; CT, chemotherapy; COMP, cyclophosphamide, vincristine, methotrexate, and prednisone. The referent group for each treatment exposure consists of subjects who did not receive that treatment. Treatment results are adjusted for NHL and histopathology. CT and BMT results are additionally adjusted for RT.
