REGRESSION
Statistical analyses were performed with the Statistical Package for Social Sciences version 28.0 (SPSS Inc., Chicago, IL, USA). Data distribution was assessed by Kolmogorov–Smirnov test. Data were expressed as mean and standard deviation (SD) for quantitative variables and sample size and percentage for categorical variables. A Logistic regression was used to assess the association between several dietary patterns/MetSSS (dependent variable) and the economic cost of the diet (€/1,000 kcal/day) (independent variable). Each dependent variable was categorized into two categories. Cutoff points were percentile 50 for healthy and unhealthy provegetarian dietary patterns and for MetSSS. The cutoff for DII was 0, as it is the cutoff for clinical relevance (Pearson's correlations between the cost of the diet and adherence to several dietary patterns were performed. Correlation analysis was adjusted by age, sex, and educational level and is shown as several graphs in the
