  1. PASI score well correlated with all the dietary components, except for protein and total carbohydrates. Correlations between variables were performed using Pearson r and Spearman’s rho correlation coefficients. After adjusting for BMI and number of parameters of metabolic syndrome, the associations between PASI score and nutrient intake were mainly preserved. Italicized p-values represent significant differences at p < 0.05
  2. SFA saturated fatty acids, MUFA monounsaturated fatty acids, PUFA polyunsaturated fatty acids
