  1. Data are mean values ± SEM of volunteers (19 post-menopausal women) classified according to their NPC1L1 and ABCG6 polymorphism variants. Changes refer to the difference between serum levels after dietary intervention with enriched beverages minus those determined at baseline. For β-Cx, values represent the final concentrations achieved after intervention
  2. Significant diferences are highlighted in bold
  3. * ANOVA test for differences between polymorphisms. Significance set at p < 0.05
