One alcoholic drink contains approximately 11-14 grams of alcohol: Regular beer = 12.8 g, light beer = 11.3 g, wine = 11 g, and liquor = 14 g
Note: Significant p-value for alcohol-folate interaction (p=0.02) in multivariate model controlling for age, pack-years of smoking and current smoking status (not shown in table)
