BMC Oral Health

Table 1 Variables recovered in MG-RAST

Variable	Description	MG-RAST name
Failed	Low quality sequences	QC failed
Unknown	Unrecognized sequence in public databases	QC unknown
Predicted	Sequence with inferred taxonomy	QC predicted
Alpha	Alpha diversity by Shannon index	ALPHA
Rarefaction	Max value of rarefaction curve	RAREFACTION
Type	Sequencing approaches	Sequence type
Taxonomy	Taxonomy at genus level	Taxonomy

The variables Failed, Unknown, Predicted, Alpha, and Rarefaction were used in the descriptive and correlation analyses. Type represents the sequencing approaches (Amplicon sequencing and Shotgun metagenomics). The Taxonomy variable contains the genera found in the samples that were used in the Principal Components Analysis
