a Adjusted for age, race/ethnicity, marital status, income, education, WHI study arm, smoking status, pack-years of smoking, body mass index, and physical activity. Results for Veterans and Non-Veterans were obtained using postestimation prediction based on the fitted model with product terms for alcohol use category and Veteran status.
b p < .05 for product term of alcohol use category and Veteran status.
