  1. ^Alpha diversity were calculated based on observed richness and significance were calculated using the Wilcoxon test (for two groups) and Kruskal-Wallis test (for three or more groups), FDR corrected
  2. #Effects were quantified with R2, and p values, as determined by PERMANOVA on weighted UniFrac distances. Significant adjusted p values (p < 0.05) are shown in bold
  3. The significant increase in alpha diversity of bacterial and/or fungal microbiome
  4. *Income level is categorize into low (< €50,000/year), medium (€50,000–€110,000/year), and high (> €110,000/year)
