  1. an = 4404; weighted, n = 60,274,698. Correlation coefficients
  2. bFactor procedure, principal component analysis. Two factors with Eigenvalues ≥1.5 were rotated and extracted. Factors were labeled according to the foods found to have the highest correlation coefficients within each factor (dietary pattern). Positive factor scores indicate that those foods are more likely to be consumed in that dietary pattern. Lower negative scores indicate that those foods are least likely to be consumed in that dietary pattern
  3. cFood categories were based on consumption data collected from a 216-item Food Frequency Questionnaire from NHANES 2003–2004 and 2005–2006. Individual foods were categorized into 30 food groups
  4. dHigh-Fat-Low-Vegetable Dietary Pattern or Prudent Dietary Pattern
