P value from test for linear trend.
P value from likelihood ratio test of interaction.
Odds ratios were adjusted for matching strata (gender, race, age), total energy intake (continuous), tobacco use (number of years of cigarette smoking: never, 1–19, 20–39, or ≥40), beer consumption (number of 12-ounce (0.4-L) servings per week: none, <1, 1–4, 5–14, 15–29, or ≥30), liquor consumption (number of 1.5-ounce (44.4-mL) servings per week: none, <1, 1–4, 5–14, 15–29, or ≥30), and education (high school or less, some college, college or more). Models for interaction by smoking duration, liquor consumption, and beer consumption included only the grouped version of the respective variable.
