  1. *For this analyses we relied on the factor weights (regression coefficient in the RRR model) instead of loadings (correlation coefficient between the food pattern and the food groups) as suggested by Imamura et al. [24].
  2. +A negative dietary pattern weight reflects a low intake of this food group, whereas a positive dietary pattern weight reflects high intakes of this food group for a person that scores high on the specific dietary pattern.
  3. Total variation explained in CVD risk factors equals the cumulative percentage in explained variation of all three food patterns derived from RRR.
