A significant effect of age (p<0.05 after Bonferroni correction; exact p-values are shown in parentheses).
Shown only for the right palm (left palm showed similar trends). Infants were considered to be individuals aged 0–12 months, children/adolescents as 1–17 years, adults as 18–59 years and seniors as ≥60 years. Abundances for the left palm are shown in parentheses. Family level abundances of greater than 1% were subjected to ANOVA analysis in QIIME. Taxa present at >1% on the left palm but <1% on the right are shown in parentheses.
