Frequency distribution of OTUs across samples. a The number of OTUs commonly observed at each frequency (in n samples). b The bar presents the read abundance of OTUs observed at each frequency (in n samples) and the line denotes the cumulative total these frequencies from the most to least frequently observed. c The embedded plot revealing the percentage of human gut bacteria in the shared OTUs based on the number of sequences
