Gut microbiome structure of different populations worldwide, including refugees. (a) A significant segregation was found in the Principal Coordinates Analysis (PCoA) based on Bray–Curtis distances between the gut microbiome profiles of individual populations worldwide, including urban and rural populations whose sequences are publicly available17,18,19,20,21,22,23, and refugees from the present study (permutation test with pseudo-F ratio, p-value ≤ 0.001). C&A = Cheyenne and Arapaho. (b) Same populations as in panel “(a)”, grouped by subsistence type, namely rural populations, urban populations, and refugees. A significant segregation as found in the Bray–Curtis-based PCoA regardless of geographical origin (p-value ≤ 0.001). The first and second principal components (PCoA1 and PCoA2) are plotted and the percentage of variance in the dataset explained by each axis is shown. Color legend in the figure.
