Fig. 6: The oral microbiome is genetically more dynamic than the gut microbiome.
From: Impact of dietary interventions on pre-diabetic oral and gut microbiome, metabolites and cytokines

Normalized histograms of the percentage of strains replaced (a) per participant and (b) per species. Percentage of strains replaced (c) per participant and (d) per species (y-axis), binned by the number of species or participants available for comparison, respectively (x-axis). Boxes show the quartiles of the data (0.25, 0.50, 0.75) while the whiskers extend to 1.5 of the inter quartile range, points beyond the whiskers are considered to be outliers. All panels are stratified by the environment, “Oral” in green and “Gut” in pink. p below the legends in the upper panels and on top of the boxes in the lower panels is between the oral and gut percentage of strains replaced (two sided Mann–Whitney U test). r, p in the legend—Pearson correlation between the percentage of strains replaced and the quantity available for comparison in each environment. n below the boxplot—number of participants or species in each bin and environment.
