Occurrence of key bacterial groups in metagenomes originating from different studies.

For 13 most common bacterial genus-level lineages and 4 bacterial families, we are showing the number of metagenomes in which they were detected in as MAGs, split by the source of the metagenomic data (the study it was reported in). The total number of metagenomes that come from each study and which were included in the Dataset 1 are shown at the bottom of the table. (XLSX)
