Question · asked by 1 review
Residence in weakly contaminated area (approx. 1-5 Ci/km2) vs Residence in non-contaminated (non-exposed) area (<1 Ci/km2): Dental caries
- Population
- Children aged 5-7 years (early school-age)
- Intervention
- Residence in weakly contaminated area (approx. 1-5 Ci/km2)
- Comparison
- Residence in non-contaminated (non-exposed) area (<1 Ci/km2)
- Outcome
- Dental caries
In early school-age children (5-7 y) from weakly contaminated areas, individual cross-sectional studies reported mostly higher but inconsistent DMFT/dmft in exposed vs non-exposed children; the review did not pool the data and drew no firm conclusion (ungraded).

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.
