Models are adjusted on sex, age, and energy intake.
aAdjusted means were obtained with ANOVA models by the level of organic food contribution in the diet. P-trends across the provegetarian score quintile are all <0.0001 and were obtained with a linear contrast test by the level of organic food contribution in the diet.
bP for interaction between provegetarian score quintiles and the level contribution of organic food to the diet.
cP-linear trend of Q*v.Q1 of provegetarian score. It reflects the linearity of the difference between the first and the other quintiles of the provegetarian score across the levels of organic consumption.
