Supplementary Methods, Tables S1 - S4, Figure S1 from Dietary Nutrient Intake, Ethnicity, and Epigenetic Silencing of Lung Cancer Genes Detected in Sputum in New Mexican Smokers

Supplementary Table 1. Association between 139 dietary nutrients and ethnicity (n = 1829)*. Supplementary Table 2. The top ten nutrient measurements in correlation with principal component 2 in either positive or negative direction. Supplementary Table 3. Association between dietary folate intake and risk for methylation (n = 1426)*. Supplementary Table 4. Individual nutrients associated with risk for methylation (n = 1426)*. Supplementary Figure S1. Principal component analysis was conducted based on 101 nutrients with no missing values in 1829 cohort members and identified four principal components that explained 59% of the total variance of nutrients with each one explaining >5% of the variance. This figure included the top nine principal components with each one explaining >2% of the variance. PC = principal component.
