Group 0 name Corresponds to the control (unexposed) group for case-control studies
Non-CMD
Group 1 name Corresponds to the case (exposed) group for case-control studies
CMD
Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
Participants in the CMD group had Cardiometabolic Risk (CM) risk defined as at least 3 CM risk factors from five: waist circumference, elevated blood pressure, elevated blood fasting glucose, elevated triglyceride and low HDL concentration in USA, RSA, and Ghana

Description: Specific oral bacterial taxa are differentially abundant (in relative terms) between study sites with and without elevated CM risk (only significantly differential exact sequence variants (ESVs) with relative abundance ≥ 1% in at least one group shown.
