Cases/controls (all such values).
Unconditional logistic regression models were used after adjustment for age.
Odds ratio (all such values).
Odds ratio; 95% CI in parentheses (all such values).
Additionally adjusted for educational achievement (categorical); race (white or other); sex; recruitment site; dietary intakes of total energy, saturated fat, folate, vitamin E, retinol equivalent, zinc, vitamin B-6, fiber, and vitamin D; BMI (continuous); physical activity (yes or no); smoking status (former, current, or never); and alcohol consumption status (former, current, or never).
Further adjusted for total intake of calcium or magnesium.
