Extended Data Fig. 4: PCoA of weighted or unweighted UniFrac distances.
From: Longevity of centenarians is reflected by the gut microbiome with youth-associated signatures
Variation in gut microbial community structure among groups (n = 1575) represented by PCoA plots based on unweighted UniFrac distance (a) and weighted UniFrac distance (b). The Adonis test and one-way ANOVA with Tukey’s post hoc test were used for all panels. Data in boxes with no common letters are significantly different in one-way ANOVA with Tukey post hoc test (two-sided, P < 0.05). Boxes in boxplots represent the 25th percentile, median, and 75th percentile and whiskers stretch to 1.5 times the interquartile range from the corresponding hinge.
