Search review questions
Each row is one question a systematic review asked: who, what, compared with what, and which outcome, with the effect it found and how certain that is. Words match anywhere in the field.

Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Intervention categories, outcome domains and clusters are a proposed key pending human validation. Clear all filters

Dental caries (carious oral microbiome) vs Caries-free / healthy oral microbiome Alpha diversity (Chao1, Observed, Shannon) · Adults providing oral (saliva/supragingival plaque) 16S rRNA microbiome samples · Adults Meta-analysis of caries microbiome studies can improve upon disease prediction outcomes. (2022) | In adults, there was no significant caries-vs-health difference in Chao1 or Observed diversity, whereas the Shannon index differed significantly (p < 0.001). | NR | Ungraded |
Dental caries (carious oral microbiome) vs Caries-free / healthy oral microbiome Alpha diversity (Shannon) · Children providing oral (saliva/supragingival plaque) 16S rRNA microbiome samples · Children Meta-analysis of caries microbiome studies can improve upon disease prediction outcomes. (2022) | In children, the Shannon alpha-diversity index differed significantly between caries and health (p < 0.001). | NR | Ungraded |
