From: ABO antigen and secretor statuses are not associated with gut microbiota composition in 1,500 twins
Microbiome diversity does not significantly differ by ABO or secretor status. Within sample diversity (Faith’s phylogenic diversity) is not significantly different (P > 0.05) across the ABO groups in all individuals (a), secretors versus non-secretors (b), or across ABO groups in only secreting individuals (c). d Microbiomes are more similar for siblings versus pairs of unrelated individuals, as measured by unweighted UniFrac distance. Additionally, pairs of monozygotic twins have significantly more similar microbiomes than dizygotic twins. However, microbiomes of pairs of individuals concordant for either ABO or secretor status are not more similar than for pairs of individuals who are discordant. This holds true when all individuals in the dataset are considered (“all individuals”) or when only one individual from each twin pair is examined (“one twin per family”). The total number of pairs of individual within each boxplot is indicated with “n = “. Significance codes: P ≤ 0.05 = *, P ≤ 0.01 = **, P ≤ 0.001 = ***, P ≤ 0.0001 = ****, not significant = NS
