DII, dietary inflammatory index; MedDiet, Mediterranean Diet; MetSSS, metabolic syndrome severity; PFP, provegetarian food pattern; SD, standard deviation. ^§Tertiles of the economic cost of the diet per 1000 kcal: T1: cost up to 4.77 €/1000kcal/day (n = 2,279); T2: cost between 4.78 and 5.86 €/1,000 kcal/day (n = 2,280); T3: cost over 5.87 €/1,000 kcal/day (n = 2,279).^‡Differences in means between groups were tested by one-way ANOVA and Bonferroni's post hoc (expressed by the letters a, b, and c).
