Dental caries during pregnancy vs Pregnant women without dental caries: Preterm birth stratified by gestational age at birth (moderate-to-late 32 to <37, very 28 to <32, extremely <28 weeks)
- Population
- pregnant women
- Intervention
- Dental caries during pregnancy
- Comparison
- Pregnant women without dental caries
- Outcome
- Preterm birth stratified by gestational age at birth (moderate-to-late 32 to <37, very 28 to <32, extremely <28 weeks)
The planned subanalysis of preterm birth by gestational age at birth (moderate-to-late, very, extremely preterm) could not be performed because of the small number of cases and lack of stratified data in the original studies.

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
