How were reference ranges and abundance scores stablished for Gut Zoomer commensal microorganisms?

Reference ranges were established using a sample cohort of 192 relatively healthy stool samples. The cut-off for the healthy reference range is between 2.5% and 97.5%, and the high-risk range are levels greater than 97.5%. The healthy reference range for each bacteria is individually determined and available in the Gut Zoomer Commensal Validation report.
