Question · asked by 1 review
Fluoride concentration relative to the acceptable range (electrometric ion-selective electrode measurement; acceptable range mostly 0.6-0.8 ppmF) vs None (descriptive proportion meta-analysis): Water samples with fluoride concentration below the acceptable range
- Population
- Artificially fluoridated public water supply in Brazilian cities (water samples under external control)
- Intervention
- Fluoride concentration relative to the acceptable range (electrometric ion-selective electrode measurement; acceptable range mostly 0.6-0.8 ppmF)
- Comparison
- None (descriptive proportion meta-analysis)
- Outcome
- Water samples with fluoride concentration below the acceptable range
In the Northeast Brazilian region, a pooled 79.7% of water samples had fluoride below the acceptable range; 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.
