HR: hazard ratio; CI: confidence interval; CNS: Central nervous system cancers; CLL: Chronic lymphcytic leukemia; AML: Acute myeloid leukemia; CML: Chronic myeloid leukemia; COPD: Chronic obstructive pulmonary disease
Totals: Camp Lejeune = 7,332 Females = 3,624 Males = 3,708; Camp Pendleton = 6,677 Females = 3,031 Males = 3,646
Causes of death that were not evaluated because the number of cases were < 2 for CL and/or CP: Testicular cancer; Male breast cancer; Thyroid cancer; Acute lymphocytic leukemia
HRs adjusted for sex, race, blue collar work (y/n) and education level; age was the time variable
Blue collar work included manual jobs such as maintenance workers, mechanics, construction workers, laundry and dry-cleaning workers, pest control workers, and water treatment plant workers
