Dental caries (ECC/severe ECC) as exposure/grouping vs Caries-free controls

Relative abundance of Veillonella spp. · Individuals assessed for dental caries, predominantly children with early childhood caries (ECC) or severe ECC (age about 1 to 4 years)

Evidence on whether Veillonella spp. relative abundance is higher or lower in children with dental caries than caries-free controls is inconsistent across 7 small observational studies; no pooled estimate was produced and the evidence is ungraded.
