* Odds ratios and 95% confidence intervals were calculated with unconditional logistic regression adjusted for age (continuous), education level (<high school or >high school), gender (male or female), total meat intake (continuous), smoking status (never, quit, or current), number of cigarettes per day (continuous), years of smoking (continuous), and year of admission (continuous).
