Multivariable model adjusted for: age, calendar time, race, height (quartiles), BMI at age 21 (4 categories), current BMI (6 categories), vigorous physical activity (quintiles), smoking (never, former quit >10 yrs ago, former quit <10 yrs ago, current), diabetes, family history of prostate cancer, multivitamin use, intakes of red meat, tomato sauce, calcium, alpha linolenic acid, supplemental vitamin E, and alcohol intake (all quintiles), energy intake (continuous), and history of PSA testing.
Models for specific case types and among men with PSA tests in the previous period to investigate possible detection bias, see text for details. Lethal cases: prostate cancer death or bone metastases; Advanced: Lethal, or Stage T3b or T4, or N1 or M1; Localized: T1 or T2, and N0, M0.
