Fig 6. Analysis of differences in the microbiota between the low-altitude Han population and high-altitude immigrant Han population using Lefse software.

Taxa enriched in the immigrant Han population are indicated with a positive LDA score (green), and taxa enriched in the low-altitude Han population have a negative score (red). Only taxa meeting an LDA significant threshold of 2 are shown. For taxa, which were defined as unclassified or uncultured, the name of a higher taxon level was added before its taxon abbreviation. p, phylum; c, class; o, order; f. family; g, genus.
