^{a} Test for trend calculated by entering a continuous term in the conditional logistic regression model.
^{b} OR and 95% CI estimated from conditional logistic regression model.
^{c} OR and 95% CI estimated from conditional logistic regression model after adjusting for mean values (1980–1990) for body mass index, physical activity, aspirin use, cigarette pack-years smoked, alcohol consumption, intake of red meat and methionine, 1980 folic acid intake, and 1990 postmenopausal hormone use.
